[396] Marcel Dupré was born on 3rd May 1886 in Rouen1 and died in Meudon, on the outskirts of Paris on 30th May 1971, Pentecost Sunday, a few hours after playing the organ for Mass at Saint Sulpice where he was titular organist.2 Described by Olivier Messiaen as ‘the Liszt of the organ’,3 Dupré was a hugely influential virtuoso and teacher whose pupils included such distinguished figures as André Fleury, Olivier Messiaen, Jean Langlais, Jehan Alain, Marie-Claire Alain, Gaston Litaize, Jean-Jacques Grunenwald, Jeanne Demessieux, Rolande Falcinelli, Pierre Cochereau and Jean Guillou, just to mention some of those who were French, all of them known as improvisers of the highest quality. Dupré was also a prodigious improviser, often concluding his concerts with an improvised four-movement symphony. His contrapuntal skills in improvisation were particularly noteworthy. In his final exam as a student at the Paris Conservatoire his improvisation on the given chant, Iste Confessor, presented the melody in a canonic treatment;4 Bernard Gavoty records how on one occasion Dupré improvised at Saint Sulpice a Ricercare for six voices with a double interior canon.5 On the basis of these facts alone the two-volume treatise of Dupré on improvisation represents a document of considerable historical interest.
The Publication of Two Volumes on Improvisation
[397] The comprehensive and systematic work of Dupré on improvisation is his Cours Complet d’Improvisation à l’Orgue.6 In this study I refer to the English translations, also published by Leduc: Complete Course in Organ Improvisation: Volume 1 Preparatory Excercises for Free Improvisation (English translation by Alain Hobbs in 1957) and Complete Course in Organ Improvisation: Volume 2 Organ Improvisation (English translation by John Fenstermaker in 1973).The second volume was in fact the first to be published, in 1925, while the first volume was published in 1937. In this study I will begin by looking at Volume One. Although the second volume was written earlier, this approach represents the order in which Dupré himself finally organised the material. Further, the size and nature of the Volume One presents an opportunity to grasp quickly much of Dupré’s pedagogical approach to improvisation.
Volume One: Preparatory Exercises for Free Improvisation
[398] The words ‘free improvisation’ in the title take some explaining. Contrary to first impressions, the kind of improvisation envisaged in this volume, and arrived at by the end of the exercises is, as we shall see, very tightly structured and controlled. One should also be aware that the terminology thème libre refers to a form of improvisation studied in the Conservatoire and used in examinations. This ‘free improvisation’ was introduced in the Conservatoire examinations in 1843.7 As we will see later, the elaborated form given at the end of Volume One is in fact a version of the thème libre. Having examined the completed form at the end of the volume we will be in a position to look back at earlier forms used in the Conservatoire and to note the contribution that Dupré made in the evolution of this element of the teaching and examination of improvisation in the Conservatoire. Maurice Duruflé, who entered the organ class of the Paris Conservatoire in 1920 while Eugène Gigout, Dupré’s predecessor, was still teaching, describes the form as follows:
The free improvisation took a form of a monothematic sonata first movement that bore no relationship with the classical allegro. It was a hybrid form in three parts, of which the first and third had more the character of an andante. The central development was more animated.8
[399] If this particular form of improvisation was, in fact, rather strictly planned and assessed in examination, one might well ask why the word ‘free’ is used at all. The word ‘free’ (libre) is used here to refer to approaches to form that are different from the ‘strict’ or ‘rigourous’ (rigoureuse). In his approach to improvisational forms, Dupré included under the heading ‘free’ such forms as the suite, variations and the symphony, while the term rigoureuse referred to choral forms, prelude, fugue and ricercare.9 His own description of the form used in the exam is:
So-called “free” improvisation in the form of an Andante movement of a sonata with center development section. The term “free” indicates the harmonic idiom is less strictly contrapuntal than for the fugue.10
An Outline of the Volume
[400] Volume One comprises twelve lessons, preceded by a preface. In the preface the author refers to some of the great improvisers of the past, such as Bach, Handel, Mozart, Beethoven and others, and while acknowledging their sublime level of inspiration and imagination, asserts that improvisation is also something that can be learnt and taught in the same way as virtuosity and technique, namely through constant repetition and patient improvement of the same passage, according to a strict discipline and method. That skill in improvising is gained through hard work is borne out by Dupré’s own practice as a student: he regularly practiced up to nine hours a day, of which seven were devoted to fugue.11 Odile Pierre, who studied improvisation with Dupré in the Paris Conservatoire, outlines how improvisation fitted into her daily plan of seven hours practice: two hours on fugue (on 4 subjects), one hour on Gregorian versets (on 4 antiphons in each of the eight modes), one hour on thème libre (two themes) and three hours on repertoire.12 Michael Murray, a private student of Dupré whose daily work also involved three hours of harmony and counterpoint, was advised by his teacher to spend two hours on repertoire and two hours on improvisation.13
[401] Lesson One begins by tackling harmonisation, beginning with the harmonisation of major and minor scales in the soprano voice, the tenor and the bass, using only the simplest of chords.
[402] Lesson Two develops this further with the harmonisation of eighty short melodies in the soprano, the pedal and the tenor, using only perfect chords and first inversions. It is also suggested that these exercises be transposed.
[403] Lesson Three addresses the idea of the “antecedent and the consequent” whereby the same phrase of a theme is heard twice in succession, each time with a different ending. Sixty antecedents are then given for the student to harmonise and improvise the relevant consequents. Only in this chapter does Dupré begin to allow dissonant chords and foreign notes. The progression from very limited harmonic resources in the first two lessons to a freer language is the first of many examples of a pedagogic device used by Dupré: a movement from deliberately narrow constraints towards greater freedom, to maximise technical mastery of the form and the language. Transposition of the exercises is again proposed.
[404] Lesson Four leads the student to improvise consequents which modulate into neighbouring keys.
[405] Lessons Five and Six introduce the student to the commentary, an answering phrase which is different from that of the theme. Dupré shows the student a way of improvising a ‘deductive commentary’ which is inspired by the rhythm and melodic contours of the theme. He begins by getting the student of improvise answering phrases which are simply transpositions of the theme onto another degree of the scale. He then shows that a simple change of interval at important points moves fragments of the theme into different positions, thus producing a new melody which is inspired by the theme but not identical with it. An example perhaps clarifies this better than words. With the following subject, a deductive commentary is made by changing the melodic intervals at three points, marked here by asterisks:14
[406] Lesson Seven teaches the student how to improvise a Binary exposition:
• Theme (4 measures)
• 1st Deductive commentary (4 measures), modulating to the dominant via the relative
• Repetition of the theme (4 measures) in the tonic
• 2nd Deductive commentary (4 or 8 measures) in the sub-dominant and its relative, concluding in the tonic
[407] It is to be noted that the schema of modulations proposed by Dupré is only an initial guide to help the beginner. This implies that a freer approach to modulation is envisaged once the student has attained a certain fluency.
In this lesson Dupré gives two examples of a fully written-out exposition, one in C major and one in A minor.15 The example in C major shows fluently moving voice-leading in the accompanying voices while the example in A minor is both sustained and restrained in its texture, with most of the movement in melody itself.
[408] Lesson Eight takes up the question of harmonisation again, giving the student themes to harmonise in the soprano, bass, tenor (in the left hand), tenor (in the bass) and alto (both hands on the same manual). Two additional exercises are then introduced: firstly, harmonising the theme in each of the outer parts with a stepwise contrapuntal movement (ascending or descending, diatonic or chromatic) in the other outer part and, secondly, harmonising the theme in the soprano with a short accompanying melodic formula repeated at different pitches in one of the inner voices. Thus the student acquires the ability to present the theme in a number of different ways, which will be used later when the full form is put together. Given the nature of these exercises, there is increased emphasis on the contrapuntal dimension of the presentation, with a more complex texture, as shown in the written examples.16 Thus one can see a progression in the presentation of the theme as the piece evolves: from simplicity towards complexity.
[409] Lesson Nine trains the student in the improvisation of a modulating bridge, rather in the style of a fugal episode. The author deals with two principal issues: a modulating structure or plan which will move from the tonic to the dominant, and the question of improvising imitations which run a melodic fragment of the theme through the different voices. The modulating plan of the bridge envisages two intermediate tonalities. Thus, a bridge from C major will begin in A minor, pass through E minor, D major, and arrive in G major.17 Dupré is concerned as to the length of the Bridge in relation to the rest of the piece, instructing the student that if the initial theme is 4 bars long, the Bridge should be no longer than 12 bars.18 As regards imitation, Dupré studies imitations at various intervals, noting that those imitations which produce a progression of fourths in the Bass are the most useful.19 After providing 20 melodic fragments on which the student is to practice modulating bridges, the author proposes the improvisation of modulating bridges using two fragments which may be inverted, using more distant tonalities, for example, a bridge from C Major beginning in C minor, moving to Eb minor before arriving at G major.20 It should be noted that in the examples which Dupré gives of a complete bridge there is a certain freedom regarding the use of the imitative figures: while the general shape and rhythm of the figure is maintained most of the time, the intervals change somewhat from time to time, and some imitations are only fragmentary.21
[410] Lessons Ten and Eleven look at the development, which is in three parts: development of a rhythmical figure, introduction of a lyrical fragment and preparation for the return. The rhythmical and lyrical fragments are presented in imitation in the same manner as the modulating bridge, except that each voice develops the fragment somewhat more at length. Dupré envisages a combination of both elements: the rhythm of the first part of the development continues in two accompanying voices in the left hand, while the lyrical element dialogues in imitation between an 8’ pedal voice and two parts in the right hand.22 As regards tonalities for the development, Dupré envisages two tonalities for the rhythmic section and one or two tonalities for the lyrical section, moving either by whole tones, ascending or descending, or by semitones, ascending or descending, with a preference for major tonalities in the lyrical section. The preparation for the return is a short passage of modulating chords on the closed swell, sufficient to create an atmosphere of expectation for the return of the theme. Dupré also envisages a ‘false return’, whereby the theme returns via a remote key. Thus an improvisation in C major will have the theme begin in B major or Db major and conclude in the tonic key. It will be noted that Dupré’s proposed treatment of the theme involves the identification of three possible melodic fragments for imitative treatment: a fragment for the bridge, a rhythmic fragment and a melodic fragment. He illustrates how these fragments can be chosen in a given theme, for example:23
[411] As in the examples given for the modulating bridge, the sample development worked out by Dupré in these lessons displays a judicious freedom in the imitative counterpoint: some imitations are partial, or inverted, or are somewhat modified as to the intervals within the melodic fragment.24
[412] Lesson Twelve gives a general plan of the improvisation with advice about registration. This is summarised in a table which is reproduced in table 1 below.
[413] It should be noted that the table given at the end of the work represents a narrower system than that described by the author within the chapters, at least with regard to tonality: the intermediate tonalities within the exposition and the tonalities prescribed in both the modulating bridge and the development represent only some of the possibilities envisaged by Dupré. This suggests that perhaps Dupré adopts a more restrictive approach for the student only as long as is necessary, until some fluency is attained. A more flexible approach to tonality is envisaged for those who can manage it.
Further Insight from the Evolution of the Thème Libre Form
[414] For the sake of this study it is not necessary to trace the full story of the thème libre in the Paris Conservatoire. Odile Jutten gives a detailed account of this.25 It is however interesting to see something of its evolution in the period before Dupré took over as professor of organ.
[415] Paul Wachs, who was a student of César Franck at the Conservatoire, published a treatise on improvisation in 1878.26 In her detailed study of the evolution of this form, Odile Jutten considers it highly probable that the sonata form which he presents in this treatise reflects the shape of the thème libre as he would have learnt it from Franck only 6 years previously, and reproduces the plan given by the author:27
1st Period: exposition of the subject, period of 4, 8 or 16 measures
2nd Period: modulation to the dominant, or bridge
3rd Period: subject in the dominant
4th Period: developments
5th Period: return of the subject in the original key
[416] It is interesting to note the plural ‘developments’ in the 4th period. In a sample realisation of the form, Wachs develops a melodic fragment from the theme, a rhythmic fragment from the bridge, as well developing the opening idea of the theme, accompanied lightly by the rhythmic fragment.28 Here I am using terminology from Dupré, but some of Dupré’s approach to form is there already in Wachs, and mostly likely in the teaching of Franck. One might also note in passing the lightness of texture throughout, ranging from one voice to four. If we compare the number of voices throughout Wach’s example compared with the examples in Dupré we find the following:29
1 voice: 2,7% (of total bars) [Wachs] / 3% [Dupré]
2 voices: 9% / 6%
3 voices: 34% / 12%
4 voices: 55% / 38%
5 voices: 0% / 15%
[417] As to any formal innovations in the class of Widor, Franck’s successor, Jutten gives no further details. A pedagogic innovation was however the introduction of a monthly class in which the evolution of symphonic forms was studied, with examples from the masters. This movement beyond a ‘school’ form to real historical examples was however short-lived.30 For insight into Guilmant’s teaching of the thème libre (1896-1911), Jutten refers to his article “La musique d’orgue les formes, l’exécution, l’improvisation” in l’Encyclopédie de la musique et Dictionnaire du Conservatiore, in which the advice as to how to improvise an andante uses clearly the same form as that outlined by Wachs.31 Interesting details include the advice to avoid using the beginning of the theme during the development (Wachs, on the other hand, does precisely this), confining modulations only to closely related keys during the development, preparation for the return of the theme with modulating passages, the possibility of more distant modulations at the end of the piece, and the perceived danger of the sub-dominant which, if over-used, destroys the tonal balance of the piece. In the absence of any direct documentation regarding the teaching of Eugene Gigout (1912-1925), Jutten has recourse to notes taken by Dupré as a jury member at examinations between 1921 and 1925.32 Here one notes the presence of more distant modulations in the development, and some canonic presentations of the theme in the recapitulation.
[418] A further step towards the thème libre as taught by Dupré in his treatise is to be seen in the teaching of Louis Vierne, who gave Dupré lessons on the thème libre during 1905-1906.33 Jean Bouvard, who was a pupil of Vierne, described Vierne’s approach to the thème libre in an article published in 1939.34 In order to compare and contrast with the approach taken by Dupré, the form and Vierne’s approach to it are summarised in table 2 below.35
[419] Although Vierne’s plan is slightly freer than that of Dupré, we can see in it many of the additional elements found in the latter’s thème libre: structuring of the modulating bridge, explicit reference to rhythmic and melodic development, including superimposition of such fragments, tonal patterns for the development, preparation for the return through modulations and distant keys, chromatic accompaniment of the theme at its return, recall of the bridge in the final section, the possibility of canon, and a conclusion over the tonic pedal. The impression is that Vierne’s approach is freer than that of Dupré. Indeed, before presenting Vierne’s plan, Bouvard stresses the element of liberty in his teaching:
Above all the rules, all the recipes, Vierne put “Music” first; to a development of a perfect structure, but in which no personal or human note appeared, he preferred the free course of inspiration. Nothing delighted him more than an original excursion into some distant keys. If he valued the free theme, it was above all as a scholastic form for developing the precious gifts of inspiration, an outline to guide and help the pupil, a constraint from which the maître knows how to extricate himself.36
[420] In her detailed analysis of materials related to examinations in the Conservatoire, Odile Jutten shows gradually increasing level of detail in the headings of Dupré’s notes taken during performances, for example:37
May Exam, 1926
• Exposition
• Bridge
• Dominant
• Development
• Return
Final Competition, 1932
• Theme
• Second entry
• Bridge
• Dominant
• Development

Entrance Exam, 1934
• Harmonisation

• Development
• Lyrical
• Return
• Conclusion
Final Competition, 1942
• Theme

[421] We can see here that Dupré came to regard as obligatory the additional elements of design which he learnt from Vierne and incorporated into his first volume.
The Thème Libre in Dupré’s Organ Class
[422] It is one thing to examine a textbook; it is another thing to see how its author uses its principles in practice. Aside from indications already seen in the record of examinations, we can gain a fuller picture by drawing on the memories of actual students of Dupré. Of particular interest is the level of freedom given to the individual student: were they obliged to follow every detail as set down in the form outlined in the treatise, or was there some level of flexibility?
[423] The emphasis in the answer to the above question varies according to the particular student, some emphasising rigidity, others freedom. Louise Girod indicates that the rules in the treatise were to be followed and that “Dupré used to say: ‘It is only at the end, when you draw the Voix Celeste that you are really yourself.’ At that point one could let go a little…”38 Suzanne Chaisemartin remembers no other form being studied other than that found in the treatise.39 Marie-Clarie Alain speaks of having to follow the details of the plan “to the letter”, even regarding registration, though she remembers Dupré smiling when Pierre Cochereau produced a crescendo to the tutti during the development. She recalls a certain freedom regarding harmonic language.40 Jeanne Joulain depicts a combination of strict control and personal expression: the thème libre was “like a kind of andante sonata, which was free only in its harmonic language, but in which the personality of each one could find free expression”.41 As to rigidity, she adds, “Some people have reproached him [Dupré] sometimes rather vehemently, for being intolerant and of demanding passive obedience. This is not accurate. He wanted above all to give us solid principles, on the basis of which the personality of each would expand.”42
[424] While Odile Pierre, who clearly admired Dupré’s teaching, speaks of minute attention to detail in the following of the plan of the thème libre, she also says that Dupré readily encouraged flights of lyricism in the central development.43 Bernard Gavoty recounts an improvisation of Jehan Alain, the conclusion of which broke the rules that Dupré had given. When Alain exclaimed, ‘Ah! I’ve gotten it wrong!” Dupré replied, ‘Make that kind of mistake often!”44 In his final exam, Jean Langlais improvised on a theme in a minor key and, contrary to the expected procedures, presented the second exposition of the theme in the dominant instead of the relative major, because he thought the effect more musical. Dupré was taken aback, and worried that the jury members, who would expect a presentation in the relative major, might vote Langlais down. Langlais’ playing was so good that Dupré remained fairly confident that he might get a premier prix. This is in fact what happened. Thereafter Dupré instructed juries to allow a second exposition of a minor theme either in the relative major or in the dominant minor.45 The incident highlights both the strengths and the weaknesses of the institution: there was the real danger of rigidity coming in the way of music, though in fact it was music that won the day.
[425] As we have seen, the thème libre was a form developed for teaching and examination in the Conservatoire. It is significant in this context to note that Dupré made no reference to such a form in his earlier volume (now Volume 2). This suggests that, in all its details, perhaps he did not considerate it as a viable form for real music making outside the walls of the Conservatoire.
[426] If the thème libre was a rather artificial form, in the hands of Dupré, the form and the exercises associated with its preparation developed a wide range of technical skills that would certainly prove useful in a range of different improvisational contexts:
• Harmonisation of a melody in any voice, with appropriate contrapuntal interest in accompanying voices
• Introduction to basic building blocks:
- Antecedent and consequent
- Deductive commentary
- Binary exposition
• Imitative harmony
• Modulating bridge
• Development with sense of key structure, imitation, rhythmic and melodic emphasis
• Analysis of thematic elements for development in the course of a piece
• The device of the ‘false return’
• Relationship between form and registration
• An overall sense of proportion regarding the length of sections within the piece
• An introduction to sonata form, albeit in slow motion
Volume Two: Organ Improvisation
[427] An overview of Volume Two of the treatise can be obtained by examining the table of contents:
Introduction
I. Organ Technique
II. Natural Harmony
III. Theme
IV. Counterpoint and Chorale
V. The Suite
VI. Fugue
VII. The Variation
VIII. The Four Symphonic Forms
IX. Free Forms
X. Appendix46
[428] As regards the overall approach indicated in this ordering of material, we can look to Dupré’s own remarks on the proper path to follow, given in an article shortly after the publication of the treatise:
At the outset one must fight against ambitious flights and trace the humblest paths, progressing slowly towards high roads. It is very important that one should take up the easiest practice first – given melodies in counterpoint, treated in the severe style of the sixteenth century masters, in two, then in three voices. Improvising in the trio form is the surest way to learn how to carry out the voices independently. When one is able to work out canons at different intervals, the study of the fugue may be started, in three, then in four voices or more.
The form of the aria, the minuet and prelude should be practiced next, as a transition between the fugue and the symphonic style, such as is found in the variation [...].
[…] As for the free forms, such as the fantasy and the rhapsody, they should be tried later as a means of enriching the talent of the improviser and giving wider scope to his imagination.47
Chapter One: Organ Technique
[429] Chapter One begins by stressing the importance of a good piano technique and indicates a minimum daily round of scales and arpeggios. A section on manual technique at the organ places great emphasis on the ability to maintain a perfect legato touch, giving exercises relating to glissando, the passing of fingers over and under, as well as finger substitution. A page on the basics of pedal technique follows. A further page outlines succinctly Dupré’s approach to rhythm and rubato, to the length of repeated notes and other issues of articulation in the context of polyphonic playing.48
[430] Four pages on registration follow, most of which is given over to a consideration of a symphonic style which adopts an orchestral approach: “one must, after realizing the exact value of each stop, observe laws governing orchestration and choose stops as if one were choosing instruments in writing a full score.”49 This leads into a detailed consideration as to how orchestral instruments may best be imitated at the organ. Some final considerations of organ stops in the own right conclude the chapter.
Chapter Two: Natural Harmony
[431] The importance which Dupré attaches to the contrapuntal aspect of improvisation, already evident in Volume One, is given explicit emphasis in this chapter on harmony: “The improviser should in no case be preoccupied with harmonization which must come to him in an immediate spontaneous manner and which must be only the consequence of the contrapuntal movement of voices.” This point is made with greater force later on:
“Contrary to belief, the harmonic flavour is not something elaborately worked out; it must come forth spontaneously. It is vain to search for pretty harmonies.” Nonetheless a harmonic awareness is vital, and so the author continues: “But to be able to identify every harmonic combination in a flash one must know how to bring back every chord to its natural source which is the immutable harmonic series given by a fundamental sound.”50 This leads to a consideration of the harmonic series and the intervals which it generates. After looking at intervals the author continues by examining 3-note chords, 4-note chords and 5-note chords built on intervals of a third, all of which, together with their inversions, are found within the harmonic series.
[432] A second section within the chapter looks at modulation by means of two symmetrical chords: the augmented fifth chord and the diminished seventh cord which, according to Dupré, though open to abuse, offer the possibility of instant modulation to any key.
[433] A final section within this chapter looks at ‘resolutions of polytonal aggregations’.51 Dupré proposes, with examples, that the apparent bitonality of complex chords can normally be resolved into simple tonality, either by the attracting power of a dominant extending to a note in false relation or by the modal series to which the notes belong.52
Chapter Three: Theme
[434] Chapter Three is built on the understanding that a quick and methodical analysis of the theme to be improvised is essential to good results.53 Dupré puts the matter succinctly: the improviser “must not ply the theme to a pre-decided form but on the contrary must adapt to this theme the form it requires and no other.”54 To further this aim, the author looks at modes, rhythms and theme analysis.
[435] The treatment of the modes comes as something of an invitation to move beyond a purely diatonic understanding to a broader, richer modal world, including ancient Greek modes, plainchant modes, Hindu modes, gypsy and Arabian modes, as well as a variety of pentatonic modes. There is also a brief concluding reference to modes which use microtones. The importance of modal colour is seen in the author’s description of the ancient diatonic modes which, using the notes of C major, he outlines as follows:
• The mode of F, the ‘Supermajor’, energetic and light
• The mode of C, the major mode
• The mode of G, the ‘Interrogative mode’
• The mode of D, the ‘Superminor’, fiery yearning
• The mode of A, the minor mode without the leading note
• The mode of E, a mode of ‘supplication’
• The mode of B, ‘depressing and inconsistent’55
[436] Dupré’s study of rhythms begins with consideration of the rhythms of Greek poetry (pyrrhic, trochee, iamb, tribrach, spondee, dactyl, etc.56). He continues with a consideration of the characteristics of some of the simpler rhythms and their connections with certain forms, for example:
• Trochee (_U), tribach (UUU): three beats (minuet and waltz)
• Iamb (U_): three beats (passacaglia)
• Spondee (_ _): four beats (march)57
[437] The analysis of the themes is treated according to a specific order of questions.58 Firstly the overall nature of the theme is determined, as to whether harmony, melody or rhythm predominate. Secondly, the key of the theme should be established. Thirdly, the truest and simplest harmony is established. Fourthly, the mode (and this includes the range of the theme, the first scale step, the last scale step, the note most frequently heard, the emotional summit of the phrase and the essential scale steps on which the theme rests) is examined. Fifthly, the rhythmic figures of the theme are examined, and the order in which they might best be developed. Finally, the question of counterpoint is examined, with the possibility of a countersubject, if the theme requires it, as well as possible imitations.
Chapter Four: Counterpoint and Chorale59
[438] Chapter four begins with exercises the ‘severe style of the sixteenth century masters’ referred to above, beginning with simple 3-part harmonisations, and progressing with 3-part counterpoint under very strict conditions.60 Exercises in canon follow, firstly 2-part and secondly with a free voice added.
[439] The student is then introduced to four chorale forms. In the Canonic Chorale, Dupré points out that canons are often fragmentary, with one voice having to wait occasionally for the canon to ‘fit’. He also notes that such canons work best at the distance of one note, especially at the interval of the fifth or the fourth.61
[440] In his treatment of the Contrapuntal Chorale, as with many other forms, Dupré not only gives advice about the form but also suggests a progressive programme of practice. He envisages imitation in the accompanying parts, either free, or based on the melody or the chorale text. He suggests that initially such imitation be practiced in a definite order of voices before progressing to something freer. He suggests beginning with 3-part treatments and then 4-part settings, and lists various dispositions of parts for hands and feet.
[441] The Ornamented Chorale is introduced to the student in two forms. The first form follows the example of Bach, using simple ornamentation of the chorale melody, with care taken not to overload the soprano. A more modern form is then suggested, in which each phrase yields fragments which are developed to form a completely new melody, each 4-bar phrase being treated independently to yield a section of about 16 bars.
[442] In the Fugal Chorale each line of the chorale becomes the subject of a short fugal exposition, with the chorale appearing in augmentation in the final voice each time. As with all these forms, Dupré gives certain dispositions or ordering of vocal entries as the basis of the student’s practice.
It is interesting to note that Dupré begins his treatment of chorale forms with the strictest kind, namely canonic, before moving to the other forms, which allow a little more room for creative flexibility. After the severe work of canonical treatment, the other forms flow rather naturally.
[443] At the end of the chapter, three more advanced forms are described: Canonic Chorale in Five Voices (two parts in canon with three accompanying parts), Fugal Chorale in Five Voices, and a form which begins as a Contrapuntal Chorale and continues after a brief transition as a Canonic Chorale. It should be noted that in all the five main chorale forms discussed in this chapter, Dupré refers to examples from the writings of J.S. Bach. The chapter concludes with hymn melodies both from Catholic plainchant and Lutheran hymnody.
Chorale Improvisation on Plainchant Melodies in the Conservatoire and in Dupré’s own performances
[444] It is interesting to note in passing that the treatment of plainchant melodies in this chapter corresponds to that envisaged in the improvisation exams of the Paris Conservatoire, the first test of which was as follows: “On a prescribed Gregorian theme, improvisation of a contrapuntal chorale in the manner of the chorale preludes of Bach.”62 The freer approach to chant typical of Charles Tournemire was not envisaged here.63
[445] As regards Dupré’s approach to the teaching of these forms in the conservatoire, Jutten’s research into the examinations of that institution yield some interesting information.64 Already before succeeding Gigout as professor of organ, Dupré was a jury member for conservatoire organ exams between 1921 and 1925. His detailed notes from the exams indicate that the favoured form for students was the contrapuntal chorale, with the theme in the pedal. Canonic chorales were rare, (only 2 out of 22 examples), while fugal chorale and ornamented chorale are totally absent. Dupré noted that in the final exam of 1921, no-one noticed the canonic possibilities of the chant, which he wrote out.65
[446] Here we see Dupré putting into practice the advice he gives in the treatise: the canon is at a fifth below, beginning at a space of two beats, with rhythmic adjustments introduced where necessary. [447] As regards developments during Dupré’s tenure as professor of organ, Jutten shows a marked increase in the standard of contrapuntal playing. In the period 1928 to 1954, canonic chorales, with vocal dispositions of 3, 4,5 and 6 voices, make up over a third of the chorale treatments presented by students in their exams. In all, 70% of chorale treatments are of one type or another that is contrapuntally demanding: canonic chorales, fugal chorales, contrapuntal chorales with a countersubject and mélanges.66
[448] We find examples of contrapuntal and canonic chorale treatment among Dupré’s own recorded improvisations in the two chorale variations which he improvised in Cologne Cathedral in 1961.67 The first is an improvisation in four voices which presents the theme in the bass, with a simple countersubject of quavers in ascending and descending scales, which moves throughout the accompanying voices:
The second variation presents the theme with a canonic imitation at the fifth:
We can see here further examples of the necessary rhythmic alteration of the theme in order for the canon to work.68
Chapter Five: The Suite
[449] Chapter Five studies the dance forms of the baroque suite, together with the Prelude and the Toccata.
[450] The chapter begins by studying the harmonic scheme of the Sarabande from Bach’s second Partita, in C minor and continues with outlining key structures in binary form for the student, using modulations only to closely related keys. The study of the Minuet follows, with a discussion about the difference between binary and ternary expositions.
[451] Outline plans for a minuet and trio are given, referring both to thematic structure and tonal structure. As in other parts of the treatise, the structures given only represent a first step for the beginning:
We have chosen the two preceding forms as the best ones with which the student should become familiar in implementing modulations. He will be able to take more liberty later. Also he will be able, after some time, to give twenty, twenty-four, and even thirty-two measures to the second sections of the minuets and trios, instead of sixteen.69
[452] Further points which are specific to the student improviser: Dupré notes that in the final section of the Minuet and Trio form, it is quite difficult to repeat accurately the content of the opening section, and the improviser must be content with a similarity of length, tonal activity and harmonic structure.70 Secondly, the author recommends beginning with slow themes and only gradually moving towards the more animated movements. Thirdly, he recommends practicing these forms, firstly in two voices, and later in three voices on two manuals and Pedal. This last recommendation is clearly not so much to do with an approach to form as the acquisition of a strong sense of the independence of melodic lines and a contrapuntal facility.
[453] The section on the Prelude analyses the preludes of Bach in Eb and B minor for organ. Dupré then illustrates how a prelude might be improvised, taking as his inspiration the fugue theme of the ‘little’ fugue in G minor. He uses 3 melodic fragments from the fugue subject and, transforming their rhythms into equal note values, uses them as theme, commentary and modulating material. After illustrating the structure of the exposition, in both binary and ternary forms, he outlines a full form with expositions in tonic, dominant subdominant keys, with appropriate modulating bridges. He notes that the subdominant exposition should be shorter so that the final key is heard as the true tonic and not the dominant of the second last exposition.
Dupré’s treatment of the Toccata
[454] The Toccata as proposed by Dupré is similar in form to the Prelude. After brief references to the toccatas of Bach and others, and a short analysis of the structure of the toccata in Widor’s Fifth Symphony for Organ, the author proposes an outline form which is broadly similar to that of the Prelude, though the sub-dominant exposition is absent: expositions in the tonic and dominant (or relative major) with modulating episodes between, leading to a recapitulation in the tonic, via a distant key a semitone away.71 Dupré envisages a formula of continuous rhythm, which accompanies the theme in longer note values. He also mentions the danger of monotony and advises the improviser to look for variety of texture.
A Toccata Improvised by Dupré
[455] We have an example of an improvised toccata in the postlude which Dupré improvised at the end of a ceremony to dedicate the Beuchet-Debierre organ at St Louis des Invalides in Paris on 8th December 1957.72 A melody in long note values is heard in the pedal:
This bears a striking resemblance to the chant Adoro Te, which Dupré used as the theme of the final movement of his Symphonie Passion:
The piece opens with 13 bars of continuous rhythm, which will continue in the manuals when the pedal theme appears:
[456] After 13 bars the piece modulates, not into the dominant, but into F# minor. Instead of a second exposition of the theme we find that the development has already begun, using the falling scale in the second half of the theme. After 16 bars of modulating development the piece arrives at a dominant pedal. The tonic return of the theme in the pedals occurs 4 bars later. The opening arpeggio motif is heard twice in the pedal, with an expansion of intervals the second time around. The full theme is then heard, with some final development of the descending scale providing a short coda.
[457] We find here that Dupré has used some of the devices mentioned in the treatise while at the same time choosing to ignore or modify other principles:
• There is a continuous formula in the hands which could be said to be loosely based on the falling scale found in the pedal theme.
• There is a theme in the pedals in long note values, though its appearance at the beginning of the piece is brief.
• There is no second exposition of the theme that might contrast to the opening exposition.
• There is a central section which moves through a variety of keys
• The theme returns in the tonic key, in a slightly developed form, leading to a short coda.
[458] One might say that Dupré has improvised here a more condensed form of toccata than that found in the treatise. This is perhaps because of the context: this is the last of eleven short pieces improvised as part of the blessing ceremony, which took the form of a dialogue alternating between Cardinal Feltin and the organ.
Chapter Six: Fugue
[459] Chapter Six is lengthy and detailed though, according to Dupré, only dealing with those aspects of fugue which are pertinent to improvisation.73 For a more detailed study of fugue, he recommends André Gedalge’s Traité de la Fugue.74 Here I will limit myself to outlining the sub-headings and observations of the more significant details. The sub-headings of the chapter are as follows.
I. Subject Analysis
[460] In the analysis of the subject, Dupré points out that the answer is best determined by discovering the ‘true stretto’ which, should it exist, is normally based on the answer.
II. Plan of the Fugue
• The Countersubject
Dupré envisages a countersubject which is short enough to be easily used in the course of the fugue. It does not coincide with the beginning of the subject. He also sees a progressive approach to using the countersubject: the student may well begin by improvising fugues without any countersubject, continue by introducing it in the exposition and finally use it as far as the dominant pedal.
• The Exposition
The author outlines, in order of difficulty, a variety of dispositions for expositions of two, three and four voices. The two plans for a two-voice fugue are the same as that in Gedalge’s work.75 The first disposition for the four-voice fugue places the entries in the following order: tenor, alto, soprano, bass. This is not the first disposition given in Gadalge,76 and corresponds to the disposition which, according to Gaston Litaize, Dupré always adopted in classes in the Conservatoire.77
• The Counterexposition
Dupré calls for a counterexposition when the subject is very short or when the final entry ends in the dominant key. He proposes schemata which place the answer and the subject only in the outer voices, for the sake of clarity.
• The Episode
Dupré is concerned as to the length of the episode: it should not be more than twice the length of the subject and should be extremely short before the counter-exposition and between the subdominant and its relative. The final episode is the longest. The author provides harmonic schemes for beginners and gives tables with the ordering of vocal entries in imitation. While this is a lot of detail for an improviser to assimilate, it represents a simplification and standardisation, representing only one of the five options listed in Gedalge.78
• Subject Entrances
In order to be able to transpose the subject correctly into any key, Dupré suggests the student re-read it in the appropriate C, F or G clefs. For those not familiar with all the C clefs this might represent a further mental burden. It was however quite normal for harmony exercises to be written in the old clefs and would have posed less difficulty than for many today.79 As regards the order of voices in which subject entries appear, Dupré gives a detailed framework of options which the student should adopt rigidly at first, freedom coming later when a certain technique has been acquired.80
• Stretto
Dupré gives detailed consideration to the use of stretto towards the end of the fugue, insisting that the first stretto and the true stretto involve entries of all voices, in the order in which they appeared during the exposition.
III Five-Voice Fugue
[461] Dupré warns against muddiness and advises that full five-part polyphony should be limited to certain key moments, following the practice of Bach himself.
IV Fugue with Two Subjects
[462] Dupré proposes a framework for the student’s initial attempts:
• Exposition of the first subject and first episode
• Subject and answer in the relative key, and second episode
• Exposition of the second subject in the principal key, and third episode
• Combination of subjects in the sub-dominant and its relative
• Stretto of the first subject
• Stretto of the second subject81
[463] This framework is very close to that given Gedalge’s outline of a scholastic double fugue.82 It is interesting to note however that, according to Delestre, Dupré’s usual way of improvising double fugues himself followed a different form, the subject entries occurring as follows:
• Exposition of the first subject
• Counter-exposition in the sub-dominant
• Exposition of the second subject in the relative key
• Counter-exposition of the second subject in the relative of the sub-dominant
• Strettos 83
The chapter ends with guidelines as to how to write a good fugue subject.
Improvised Fugue: Conservatoire and Dupre’s Performances
[464] An examination of Dupre’s teaching in the conservatoire shows that he used the structures seen above in his teaching and examinations. Under Guilmant the improvised fugue followed the classic ‘scholastic’ form: exposition – counter-exposition – three episodes alternating with subject entries in related keys leading to stretto. Guilmant did not impose the use of the countersubject beyond the counter-exposition, but he did insist that the subject entries in the relative keys appear in inner voices. Under Gigout the standard was certainly lower than that which Dupré would later develop in his class. In his notes as a jury member from the final exam of 1921, Dupré wrote:
No-one made a fugal entry in an inner voice, except Duruflé in the tenor, without bass. No-one saw the stretto at one beat. No-one did more than one stretto aside from the true stretto. 2 girls did the same episode on a fragment foreign to the subject.84
[465] In 1927 Dupré gave a note to the jury with the following details:
• In principle the fugue is in the tenor or the alto.
• There is a counter-exposition if the subject does not modulate at the end
• It occurs in the outer voices, beginning with the voice which exposed the subject
• The 1st stretto, distant enough, has four entries, in the same order as the exposition.
• The true stretto, generally on the dominant pedal, has four entries, in the same order as the exposition.85
[466] The following plan, for the purpose of assessment of improvised fugues in 1928, shows a high level of detail:
• Countersubject
• 3rd voice
• 4th voice
• Episode
• Counter-exposition
• Response
• 2nd episode
• Relative
• Response
• 3rd episode
• Sub-dominant
• Response
• 4th episode
• 1st stretto
• True stretto86
[467] The technical level was thus very high, and corresponds to that indicated in the treatise. Dupré himself improvised scholastic fugues, an example of which is that on a subject of Maurice Duruflé, recorded in 1949:
• After the first episode the subject is in the tenor with the countersubject in the pedal
• The answer is in the alto, with the countersubject in the soprano
• The sub-dominant statement of the subject is in the soprano, with the countersubject in the bass
• The answer is in the bass with the countersubject in the soprano
• Stretti: 1st stretto, true stretto, stretto at the octave, stretto at the 4th, stretto in contrary motion and finally stretto with augmentation in the pedal87
[468] We can see here that Dupré not only followed the plan used in class and in the exams, but also went further, concluding with 7 stretti in total.
[469] We also know of improvised fugues where Dupré felt free to adapt the form. Jeanne Demessieux remarked in her diary that when Dupré improvised fugues based on chorale melodies, he often played the full chorale as the final climax after the stretti.88 She also observed that final sections of his fugues in St Sulpice frequently exploded into toccata style, moving well beyond the form presented in the treatise or taught in class:
It is under these vaults that one had to hear Dupré improvise a five-voiced double fugue, with multiple stretti in augmentation, diminution, inversion, with continually increasing interest, bringing about an irresistible crescendo, at the summit of which would explode a toccata, the theme further enriched by rhythmic alterations.89
Chapter Seven: The Variation – The Tryptique90
[470] In Chapter Seven, Dupré notes that variations will tend to be rhythmic, melodic, harmonic or contrapuntal, and gives musical examples from history. The chapter continues with a treatment of variation technique in order of difficulty: air with variations, passacaglia, and variations in the modern style. The air and variations, envisaged as a two-part form, follow the procedure found typically in French Noëls, along the following lines.
Melody of the theme in the right hand, with melodic variation in quavers:
Melody of the theme in the right hand, with quaver counterpoint in the left hand:
Melody of the theme in the right hand, with melodic variation in triplet quavers:
Melody of the theme in the right hand, with triplet quaver counterpoint in the left hand:
Melody of the theme in the right hand, with melodic variation in semiquavers:
Melody of the theme in the right hand, with semiquaver counterpoint in the left hand:
Theme harmonised in four voices with quaver counterpoint in the pedal:
[471] Dupré’s treatment analyses the nature of each variation of Bach’s Passacaglia in C minor. He also lists the rhythms used in the piece as a model for the student, adding others. He also adverts to the possibility of canonic variation. A fairly free approach to the number and character of variations is adopted, though rhythmic and harmonic variations are to be used economically, and the presentation of the theme in other keys is not envisaged. A progression of musical interest from one variation to the next is proposed.
[472] Dupré’s treatment of ‘variation in the modern style’ focuses on harmonic and rhythmic variation. As a working exercise he proposes that the student improvise harmonic litanies where the same melodic fragment is presented in a variety of harmonisations, before applying harmonic variation to a whole theme. Under the heading of rhythmic variation, he proposes that the student present the same theme in a variety of rhythmic guises: chorale, march, tarantella, aria etc.
[473] Having studied a variety of forms in the treatise, Dupré proposes the tryptique as a larger form, and provides a table and a list suggesting various ways of constructing an improvisation in three movements using some of the following: prelude, chorale, variation, fugue, toccata. His comments regarding the above show an approach we have seen elsewhere in his work:
We would not pretend to set this table down as law: performance can make any arrangement acceptable. These are only suggestions meant as a guide in preliminary work, which can be varied infinitely. The same holds true for the following groupings. They are far from including all possible combinations, but are sufficient to open a path for the student.91
[474] He proposes such a form as most suited to themes of a serious nature, for example Gregorian melodies, Lutheran chorales, passacaglia themes and fugue subjects of a melodic nature.
Chapter Eight: the Four Symphonic Forms92
[475] We have seen throughout the treatise that the discussion of form occupies a central place in Dupré’s considerations, though in many of the chapters this is complimented by a learning itinerary whereby the student acquires certain harmonic and contrapuntal skills, as well as a progressive insertion into the particular form. Coming late in the treatise, the treatment of the symphonic forms arrives at a moment at which the student has already become a very skilful improviser and the focus thus centres to a much larger extent on form alone.
[476] As regards the Allegro, Dupré suggests a ternary exposition of the first theme if it be short, a binary exposition if it be longer. For the bridge to the dominant or relative major, a key structure of two neighbouring keys is proposed, and various examples are given. The entry of the second theme before its tonality is achieved is proposed as an elegant option, and a ternary form is laid down as the norm. The risk in the development, as the author sees it, is that the improviser will “wander from key to key, alternately stumbling from platitude to incoherence”.93 Accordingly, Dupré advises the adoption of a tonal plan of five or six tonalities, and lists a number of means of musical development, which would be employed in order of increasing interest: repetition, sequences in the same voice, sequences by imitation, inversion, canon, changing of intervals, inversion of notes, changing of respective values, changing of rhythm. Dupré’s consideration of the recapitulation includes the classic device of transposing the bridge to the sub-dominant. The device of an introduction, which returns at the beginning of the development, is also mentioned, along with considerations of the coda.
[477] Under the heading of the Andante, Dupré focuses on certain forms:
• The Song without Words, a tripartite piece in which a number of combinations of binary and ternary forms are suggested, the final (recapitulation) being rather short.
• The Andante with two Themes, which uses the allegro form in miniature.
• The Andante which presents the theme three times, with two developments between.
• Andante with variations
• Andante in the form of a simple exposition, when the pace is very slow.
• Fugal form, a somewhat reduced form of fugue
[478] Particular reference is made in the andante section to historical models, especially the nocturnes of Chopin. While Dupré generally proposes a fairly rigorous approach to form, certain remarks regarding the central section of the Song without Words show a keen awareness of the danger of rigidity:
We are purposely avoiding making the succession of tonalities any more precise, and we advise the student not to imprison himself in a few formulas he has fabricated himself… Symmetry must make itself felt in the fixed general order, but it must never smother spontaneity. It is unbearable when rigorously applied to detail.94
[479] The Scherzo is examined firstly as to its form and, drawing on a number of historical examples, Dupré points to the minuet-and-trio form, as well as the allegro form with two themes as possible alternatives. The second element for attention is rhythm and, in particular, the interplay of binary and ternary rhythms. As in many other sections of the treatise, Dupré proposes an itinerary of practice, whereby the student chooses a particular rhythm and applies it rigorously to each section of the form being studied, be it exposition, development, modulating section etc.
[480] The finale is examined by Dupré under the heading of the rondo form. As a plan for practice he proposes firstly the simpler form which consists of refrain and verses, with contrasting tonalities. The second, more complex, form combines the bithematic sonata form with the rondo. Here the first and third verses serve as bridge passages between the first and second themes within the sonata framework.
Chapter Nine: Free Forms95
[481] Here the author briefly proposes models from the literature for the fantasia, the rhapsody and for descriptive pieces. In the latter he notes that the picturesque element will be furnished by the accompaniment. The chapter concludes with a summary of the forms studied in the treatise and how they interrelate.
Appendix: Roman Catholic Services96
[482] The appendix examines the various moments of the Catholic liturgy where improvisation has a proper place, and proposes suitable forms for each. It also takes account of the sacred nature of the liturgical action, urging restraint as to rhythm and changes of registration. It also gives advice about improvising in a large stone building, where harmonies need to be clearly articulated and changes of dynamics are best taken slowly.
The Pedagogy of the Treatise
[483] A global look at the treatise reveals certain key ideas, principles or procedures favoured by Dupré:
Importance of form
[484] The question of form appears at every turn of the treatise and is a central concern. Dupré once said that he did not conceive of music without form.97 In this respect the treatise has sometimes been compared to a work on composition.98
Progression from simplicity to complexity
[485] The treatise is however more than a discussion of form; it gives the student an itinerary of study, which includes progression from simpler forms to more complex ones, for example in his treatment of fugue, variation and rondo.
Progression from rigidity to freedom
[486] Rigid adherence to certain forms is proposed as an initial training and, though the author does not say this, it seems that the motive is to make sure that the student’s technical development is complete. Rigidity in many places gives way to greater freedom once the student has made progress. We see examples of this in his treatment of the contrapuntal chorale, minuet and trio, fugal episodes and form of the tryptique. When one moves on to the fully-formed improviser, one would expect, by extrapolation, still greater freedom, and this is what we will find when we look in more detail at some of Dupré own improvisations.
Development of Contrapuntal skills
[487] The independence of voices is cultivated from the beginning, with high levels of contrapuntal competence being the final aim. This is also reflected in the particular emphasis on contrapuntal skill which Dupré brought to the class of the Paris Conservatoire, and also reflects his own innate abilities.
A treatise rooted in the historical repertoire
[488] While some of the formal ‘recipes’ given in the treatise seem somewhat abstracted from the historical repertoire, they are based on an analysis of examples from the repertoire, and the treatise is in fact replete with references to the works of particular composers. We find references to the following (the number in parentheses indicating the number of references: Bach (33), Chopin (34), Beethoven (23), Franck (12), Wagner (10), Liszt (8), Mozart (8), Schumann (7), Schubert (3), Berlioz (1), Chabrier (1), Debussy (1), Dukas (1), Fauré (1), Handel (1), Ravel (1), Saint-Saens (5), Stravinsky (1), Weber (1), Widor (1), Balakirew (1).
Variations on Adeste Fideles99
[489] Reference has already been made to Dupré’s own improvisations by way of commentary on particular sections of the treatise. It is interesting and useful have a more detailed look at some examples.
[490] The Skinner Organ Company had a studio in New York City which possessed 3-manual organ with 76 stops and a ‘player’ mechanism whereby performances could be recorded on perforated rolls.100 Dupré recorded a set of improvisations on “Adeste Fideles” on this instrument in 1929. Because the performance was recorded as perforations on the roll, it became possible to translate this into musical notation with great precision. Rollin Smith reconstructed the performance and edited a playing edition, which was published in 1974. As this improvisation dates from that period in Dupré’s life when the two volumes of the treatise were written, it invites some comparison between his written theory and his own improvisational practice.
[491] The piece begins with a straightforward four-part harmonisation of the theme, mezzo-forte. The first variation has, initially, the appearance of a contrapuntal chorale, with a thematically related countersubject in the right hand:
[492] A curious change takes place however with the second phrase of the tune: instead of continuing with the exact notes of the tune, the left hand presents the notes a third higher than normal, beginning on the note ‘B’. It represents a change in the tune and also results in ‘consecutive fifths’ between the solo and the bass and ‘consecutive octaves’ later between the tune and the alto voice which, in this particular context, sound out of place. After this phrase the texture changes with a brief interlude of 2 bars for both hands on the swell. One has the impression that there was here a lapse of concentration or a simple error in the presentation of the tune and that the improviser changed the texture in order to catch a moment of repose to find a new way forward. From this point onwards the parts are reversed, with the tune in the right hand and the countersubject in the left hand. The tune is no longer a presentation of the chorale itself but a free invention based on those aspects of the melody already used. While the first half of the variation moved towards the dominant chord, this second half moves through the subdominant area (A minor) and concludes in the tonic. Thus what appeared initially as a contrapuntal chorale is transformed, perhaps because of a mistake, into a ‘free’ binary exposition based on the opening phrases of the chorale. There is a poetic touch at the end, where the semiquaver motif of the countersubject appears briefly in the principal melody in the right hand.
[493] The second variation, beginning with a transition into E minor, is very free in what Dupré would call the ‘modern style’. This lively variation begins and ends in E minor, moves to B minor in bar 4, and back to E minor by bar 8, with constantly shifting tonality thereafter. The motif used in the countersubject of the first variation re-appears, this time transformed into a triplet rhythm:
The first notes of the chorale also appear as a recurring motif, for example:
Finally, the descending scale in the last phrase of the chorale is, perhaps, the inspiration behind a number of decorated scale passages such as the following:
[494] The generally detached quality of texture applied to the swell reeds is an instance of the principle enunciated in chapter one of the treatise, on organ technique: “Smooth polyphonic music is not good with reeds. That is why they are not used in fugues and why one should energetically release chords played by reeds.”101 After the variation proper concludes, there are three bars of slow transitional chords on the swell Flute Celeste, leading to the next variation, which is in Ab Major.
[495] The following extract from the third variation (bars 3 and 4) gives a feel for the style and texture:
[496] A number of effects combine here to produce a ‘hazy’ effect: the interplay of binary and ternary rhythm in the pedal, the combination of compound and simple rhythms between the pedal and the left hand, the use of the Voix Celeste and the Chimes, and the relatively thick texture of six voices. Most of the variation is in Ab Major, with modulation to tonalities a 3rd apart towards the middle of the piece, and frequent chromatic enrichment of the harmony. A five-bar transition of rhetorical flourishes concludes on a dominant seventh chord of B, leading into the next variation, which begins in E minor.
[497] The fourth variation treats the opening notes of the chorale in fugal style. It begins on the Great, mezzo-forte, and concludes with a crescendo to fortissimo over a dominant pedal. The word ‘fugal style’ is used advisedly, as Dupré improvises here a variation which uses fugal technique very freely, with a number of departures from scholastic practice:
• The exposition is in the relative key, of E minor102
• There is no consistent countersubject
• The first episode uses the opening notes of the fugue in F major before arriving at its destination in A minor
• There are no strettos
• The fugue ends on a dominant seventh chord of D, which prepares for the concluding variation, which is a short toccata in G major
[498] Since this variation is not a free-standing fugue but part of a series of variations, Dupré evidently felt free to do something relatively free, in contrast to the rather demanding approach envisaged in his chapter on fugue.
[499] The final variation is a short toccata which, aside from some chromatic shifts towards the sub-dominant, remains in G major throughout. It begins with a traditional texture which presents the theme in long notes in the pedal, with repeated semi-quaver chords repeated in the hands:
[500] This kind of toccata figuration was evidently a favourite of Dupré: it appears in a number of his other improvisations103 and at the end of his Variations sur un Noël104:
[501] The movement is a free elaboration of the opening phrase of the chorale. It remains in G major throughout. The theme appears first in the pedal (8 bars); an imitative dialogue of thematic material then occurs between the top of the right hand and the pedal (4 bars), five more bars lead to a dominant seventh chord; the theme reappears in the pedal for 5 more bars, with a slight variation in the texture of the manual toccata figure, and the piece concludes with a coda of 6 bars of emphatic chords.
[502] With the exception of the fugal variation, these variations could be described as tending towards variation ‘in the modern style’ as enunciated by Dupré in his treatise:
• Increasing importance of harmonization, which tends to deform the initial theme by the repetition and amplification of each fragment
• Individualization of each variation by rhythmic transformation of the theme, more and more pronounced.105
[503] While one might have expected more contrapuntal devices in the fugal variation and more tonal variety in the concluding toccata, the economy shown by Dupré in these respects is perhaps an illustration of the advice he himself gives:
However when the student later attempts a suite of variations, he should avoid giving the impression of a succession of pieces which are independent of each other. Each variation, as we have already said, must be characteristic but at the same time be an integral part of the entire piece.106
[504] These two variations also illustrate Dupré’s freedom in relation to form: the fugue and the toccata were not forms decided once and for all, but open to adaptation to the particular situation. Further creative freedom is seen in the variety of tonalities adopted for the variations and in the use of modulating transitions where necessary, neither of which are mentioned in the treatise. One should note also the manner in which Dupré responds to the tonal resources of the instrument, matching a variety of instrumental colours and musical forms. Later we will see that a smaller instrument inspires a different approach to theme and variations.
Seven Improvisations on the Organ of Paul Hoehn
[505] In 2005 a series of 7 improvisations of Dupré was published by Hans Steinhaus, Felix Gubser and Alex Hug.107 According to the foreword of the edition, these improvisations on Paul Hoehn’s house organ were recorded, probably transferred onto records, transcribed and presented to Dupré for approval and correction. It seems that Dupré’s corrections, whatever they may have been, were honest: in bars 47 and 54 of the first improvisation we find consecutive octaves and fifths respectively which, though of little concern in the context of a live improvisation, would probably not have survived in a written piece in this fairly classical idiom.108 Each improvisation is based on a chorale melody. The title of each improvisation includes the dates of performance: 5th February 1938 (improvisations 1,2,3), 4th October 1935 (improvisations 4,5,6) and 7th May 1930 (seventh improvisation). Compared to the Skinner Organ referred to above, the organ used was a more modest two-manual instrument with 19 stops.109 The advantage of studying these (as well as the preceding improvisation on Adeste Fideles) is that they are close to the time of the treatise. It appears that Dupré’s improvising style evolved: in later years, his improvisations became more restrained and more classical in tone. In 1955 André Fleury assisted Dupré at a recital at which he improvised a loud, flamboyant conclusion to his toccata on Ave Maris Stella, after which he exclaimed, “Ah, dear Mâitre, you bring me back twenty years!”110 We can take it that the relationship between the written treatise and the live improvisation is well attested by examining these texts.
Improvisation 1: Der Mond is aufgegangen
[506] The chorale in question is an evening song which flees from the vanity of the world to peace in God.111 The improvisation consists of theme and six variations, with a coda. It will be interesting to note the very different manner in which these variations are constructed, compared to those on Adeste Fideles. There are no indications of registration dynamics or tempo on the score.
[507] The theme is presented very simply in the soprano voice, with accompanying voices in left hand and pedal appearing only at cadential moments, as typified by the opening bars:112
[508] It is interesting to note in passing that a similar texture appears at the beginning of Dupré’s later composition “Matines”, (the first of Trois Hymnes, Opus 58)113 which, though in a very different harmonic style, is also in the form of theme-and variations. The first variation is a simple bicinium with the theme in the right hand and continuous quavers in the left hand. The second variation presents the theme, again in the right hand, with semiquaver triplets predominating in two accompanying voices in the left hand. It is clear from the layout of parts that this was played on one manual. In this and succeeding variations Dupré allows himself to vary slightly some of the note values in the cantus firmus. The third variation is a four-part harmonisation of the tune, with a semiquaver countersubject in the pedals:
[509] The semiquaver movement is occasionally taken up into one of the other accompanying voices. This variation seems to be more about the display of pedal virtuosity than any particular contrapuntal interest. The opening notes of the chorale melody are changed in the first phrases, the improvisation here just following the general outline of the original tune. There is also a short coda of 4 bars. The fourth variation presents the tune in the left hand, with semiquaver figuration in the right hand, and a ‘pizzicato’ pedal line:
[510] As can be seen from the opening bars, this variation is more ‘orchestral’ than contrapuntal. It is interesting to note that the chorale melody is in the soprano range, with the result that the accompanying right hand figuration occupies a region only slightly higher, which leads to much overlapping. It would have been helpful to know the original registration for this movement as well as the tempo. There is, as in the previous variation, a certain freedom note only as to the note values of certain notes within the tune, but also as to their pitch.
[511] The fifth variation, though more sedate (mostly crotchet movement), is considerably freer. A binary movement that uses certain motifs from the tune:
• 6 bars: the opening notes of the tune are treated sequentially over a tonic pedal, moving to the dominant chord
• 5 bars: the opening 4 bars of the tune heard in the dominant key, with an extra bar added
• 3 bars in the sub-dominant relative with contrasting material
• 8 bars in the tonic key
[512] The sixth variation returns to a more direct treatment of the tune, as follows:
[513] The final section, marked ‘coda’ on the score, presents the theme in a four-part harmonisation, with an ascending crotchet movement in the pedals and chromatic colouring in the inner voices:
[514] One is reminded here of the manner in which the theme is handled in the conclusion of the thème libre.
[515] Looking at these variations as a whole, one notices first of all the different approach to those on Adeste Fideles. While there is some lively pedal work in the third movement and a more orchestral approach in the fourth movement, these are still more restrained as to harmony and texture than the Adeste variations: we find nothing to compare with the flamboyance of the second variation, the harmonic colour and complexity of texture of the third and the brilliance of the final toccata of Adeste. Unlike the Adeste variations, these variations remain in the tonic key. The text of the chorale itself, which Dupré may or may not have seen, is in itself a call to restraint, but we will see that nowhere in this publication are the improvisations as colourful as those on the Skinner organ. Since these Zurich improvisations date from different years, one can safely conclude that the common denominator is the instrument itself, or perhaps the tastes of the person for whom these were originally improvised. Dupré is responding to the instrument with a more ‘classical’ type of improvisation.
[516] One notices also the rhythmic progression, where the accompanying counterpoint moves from quavers (variation1) to triple quavers (variation 2) to semiquavers (variation 3). This is an application of the form envisaged in the treatise under the heading of ‘Air and Variations’, though with some important adjustments:
• These variations are only contrapuntal, whereas every second variation in the treatise is melodic. This means also that the faster moving rhythms (quaver, triplet, semiquaver) remain in the accompanying voices and are never heard in the top voice.
• While the treatise proposes variations for only two voices, these variations present three voices (variation 2) and four voices (variation 3).
• The semiquaver countersubject is played on the pedals instead of on the manuals.
• Instead of having melodic variations alternating with contrapuntal variations, Dupré adds three more variations and a coda.
[517] We can see here that Dupré applies some of the formal resources given in the treatise without feeling imprisoned by them.
Improvisation 2: Kehre wieder, kehre wieder
[518] Here is an summary of this improvisation.
• Eleven bars of quaver movement over a tonic pedal (E Major). Dupré takes the opening notes of the tune and, modifying them, uses them as the basis of continuous quaver movement:114
• The other voices take up the theme, freely modifying it, with entries at the octave and an octave and a fourth.
• Two modulating bars, leading to a pedal in the dominant key: motif in the pedals, crotchets.
• Eight bars in B Major: a brief recurrence of the opening motif, in quavers; five bars later, this motif appears in crotchets in the soprano voice, later in the pedal.
• Five bars in A Major: sequential treatment of the opening motif, inverted, followed by the theme in crotchets.
• Five-bar Modulating passage of chromatic harmony, developing the interval of the rising 4th, moving through Bb and C, leading to a dominant pedal.
• Five bars on the dominant pedal.
• E major: Four bars of the theme, in crotchets.
• C major: three bars of the theme, note values slightly augmented.
• Six bars of chromatic modulations, developing sequentially the upward leap and downward scale of the theme:
• Two bars of dominant pedal, over which the opening motif of the theme is heard at various pitches, followed by two bars dominant 7th,with descending quaver scale passage in the pedals.
• Harmonisation of the chorale in E major: 6 bars.
• Conclusion, including scale passages in the pedals, a brief reference to the second bar of the tune, and a reference to the final notes of the tune.
[519] There is no indication of registration or tempo, thought the texture (four and five voices, with mostly quaver movement) suggests a mezzo-forte registration as a minimum, and andante con moto as a minimum speed.
[520] How might this piece be related to ideas in the treatise? The first 42 bars show similarities with the prelude form as outlined by Dupré.115 The form is however used rather freely by Dupré:
• The first exposition runs the motif through three voices instead of two, including intervals of entry other than the octave, and a fourth voice enters without the motif.
• The second exposition give the theme after a short pedal on the note of the dominant, and the theme occurs in crotchets instead of quavers, this time in the right hand and the pedal.
• In the third exposition the motif appears inverted, in only one voice. This corresponds to the concern in the treatise that this exposition be short, though its exact form is different.
• The fourth exposition, far from ending the piece, is very short and leads into another modulating section.
• The music that follows (modulating development of material, leading to restatement of the theme) could be viewed as incorporating a ‘second development’, as envisaged in the section of the treatise on the andante.116
[521] Like the other improvisations so for, we see an awareness of the usefulness of certain forms, coupled with a freedom to adapt to the particular situation and inspiration of the moment. The strict structure of the treatise has given way to something more fluid yet, at the same time, structurally sound and satisfying.
Improvisation 3: Ad nos, ad salutarem undam
[522] The original theme, in C minor, 6/4 time...
... is transformed into C major, common time...
... and begins over a tonic pedal, rather in the manner of the prelude form already seen. In bar 13 the theme reappears in the dominant key, again over a pedal. In bar 21 it reappears in quavers over a ‘D’ pedal (dominant pedal of the dominant) and later a ‘G’ pedal (dominant pedal). The expected return to the tonic is delayed by dramatic sequences with thematic material in the pedal (bar 29ff):
[523] The theme returns in the tonic in quaver values (elegantly beginning before the tonic key is re-established) in bar 32. In bar 40 new elements from the theme...
... are now introduced and developed:
[524] The dotted rhythm here, not entirely absent before, appears more regularly from now on. At bar 46 we arrive at a dominant pedal, over which we hear the original motif, now with some dotted rhythms added. At bar 54, instead of resolving onto the tonic, the harmony moves, by a relationship of a third, to Eb. This harmonic surprise is perhaps similar to that in the last improvisation where, at a similar moment in the piece, the dominant chord, B major, instead of resolving onto E major, ushers in a new development section beginning in C major. The motif continues, with constant modulation until we arrive at another dominant pedal at bar 60.
[525] After seven bars of dominant and related harmony, we arrive at a fff-statement of the theme as a majestic chorale, which moves towards E major, before finally concluding over a tonic pedal, bars 88 to 94:
[526] An overview of the piece suggests some relationship with the prelude form given in the treatise: sequential treatment of thematic material over 4 pedals: tonic, dominant subdominant (which moves into a short dominant pedal, again, perhaps as an antidote to any undue shift of balance towards the sub-dominant) and tonic with, as before, a variety of rhythms. As in the last improvisation, there is a tonal surprise towards the end: in this case the fourth pedal, instead of concluding the piece, ushers in a new development of material. What is completely new here is the lengthy chorale section which concludes the work. Overall Dupré shows himself free both in relation to the original chorale tune itself and to the form of the piece. No form is written in stone.
Improvisation 4: Dir, dir, Jehova will ich singen
[527] Following a pattern we have already seen, this improvisation opens by taking the opening notes of the chorale...
... and uses them as the basis of beginning in the manner of the ‘prelude’ style:
[528] As before, we see the prelude form, but not exactly in the manner proposed in the treatise. There is also a degree of freedom in relation to the various entries of the theme: the second entry is tonal, the third entry, though beginning on the same note as the first, is a transposition of the tonal entry, and the final entry begins on neither the tonic nor the dominant note, and is only partial. The tonic pedal section continues with more imitative treatment of the motif and achieves tonal variety by chromatic incursions into G major, A minor and D minor. Here is a delicate tonal balance of dominant and subdominant colouring which gives a certain coherence and variety to the exposition of the theme.
[529] The tonic pedal continues until bar 12. In bar 11 a new motif, doubtless inspired by the second phrase of the chorale, leads into a new imitative section:
[530] There is a certain artistry in the fact that this new material appears before the end of the tonic pedal and before any new modulations take place.
In bar 15 the music moves to the dominant, though there is no dominant pedal. The movement to the dominant is followed by a statement of the third line of the chorale at bar 19. An interesting detail: though this line of the tune is played at its original pitch, based on the tonic key, the inherent possibilities of a strongly subdominant emphasis are used to keep the piece tonally fresh. The overall effect is of a turn to the subdominant.
[531] From bar 26 a modulating section begins based on chords whose roots are a fifth apart. From bar 32 the chromatic language of the piece tightens. Given the shape of the piece thus far, one might have expected a triumphant return of the tonic but instead the main theme returns in the key of A major. It returns, not in the quaver figuration of the opening, but in the shape of the first two lines of the chorale tune itself, in a contrapuntal texture. This leads, from bar 41 onwards to modulating sequential development of the opening notes of the chorale. Finally, by bar 51, we have truly arrived in the home key, with a full statement of the chorale, with running quavers in the pedals:
Any student who had really practiced the final variation of the ‘air and variations’ form117 would be capable of this ending.
[532] Viewing the improvisation as a whole we see a creative use of the prelude form, using sometimes a continuous quaver formula and at other times the metre of the chorale itself. The continuous formula appears in fact only at the beginning and is never heard again. We see a careful balancing of tonic, dominant and subdominant tonalities, both within the exposition over the tonic pedal and within the first 32 bars as a whole. As with the last two improvisations, at that point where a prelude form might have concluded, we see a departure into a new section with its own development, in a key a third away from the tonic (Kehre wieder: flattened sub-mediant; Ad nos: flattened mediant; Dir, dir: the major key on the sixth degree). We can see in all three pieces a certain formal similarity, but the solutions are different each time. One senses a musician who achieves the balance of having an eye to overall shape while at the same time playing quite spontaneously at any given moment.
Improvisation 5: Wer nur den lieben Gott lässt walten
[533] This improvisation is a more straightforward chorale prelude: a right hand solo with left hand and pedal accompanying, adagio:
[534] One notices the hint of preparatory imitation in the accompanying parts at the beginning, and the slight chromaticism, as well a flexible approach to the note values of the tune, which will appear very slightly ornamented at times. The chromatic language surfaces and recedes at various moments of the piece, which has two short interludes for the accompanying parts, in the traditional manner. In the first interlude the accompanying parts anticipate not so much the notes of the next line of the chorale as its overall melodic shape. In the second interlude the ascending line of the previous part of the choral is echoed. One particularly interesting feature: while the chorale tune itself is finished by bar 34, Dupré extends the piece by restating the first line of the chorale in the subdominant, with an answering phrase and a final pedal of four bars. The last four bars of the piece recall something of the last three bars of the chorale. One sees in this improvisation a combination of harmonic rigour as to choice of chords and voice leading, combined with flexibility as to the chorale tune and the form.
Improvisation 6: Ihr Knechte des Herrn, den Meister tut kund!
[535] Described as “Allegro maestoso”, this piece begins with an exposition based on the opening two phrases of the hymn, beginning with the theme in the pedals:
In bar 9 the theme appears in the top voice, in D major, followed by a commentary of chromatically descending harmonies. The pedals take the theme up again in Bb major at bar 21. This section concludes on a dominant 7th at bar 33.
[536] The registration reduces to mf for the next section, which is fugal, taking the first four bars of the chorale as its subject:
• Exposition: Tenor, alto, soprano, bass, with no consistent countersubject. The opening notes of the subject receive a tonal answer.
• First episode: passages or running quavers alternate between the voices. These might be said to relate generally to the quaver lines found in the accompanying parts in the exposition, or perhaps to the melodic outline of the second line of the chorale, but there is no obvious thematic link.
• Relative key: the subject appears in the soprano voice and, after a short 2-voice interlude on the swell, p, the answer appears in the pedal.
• Second Episode: a longer episode, from bar 72 to bar 94, returning to the Great at bars 75 to 77, with a crescendo at bar 87.
• Return of the theme at bar 95 in block chords over a decorated dominant pedal:
• Bars 101 to 135 remain substantially in Bb, reiterating various elements from the theme.
[537] One might describe the improvisation as a fugue interposed between two homophonic treatments of the theme. The fugue is free and condensed: no consistent countersubject, no sub-dominant entries of the subject, no strettos. Like the other improvisations we have examined so far, this is only loosely related to anything Dupré gives in his treatise, and shows a creative adaptability as to form.
Improvisation 7: Variations sur un theme de Haydn
[538] This improvisation is based on the theme and variations of the same name by Johannes Brahms (opus 56b). Improvised in Db major instead of the Bb key of the original, the improvisation is not a set of variations but a piece based on those variations, in three sections: Theme – Development – Recapitulation. First Section: Bars 1 to 54 present the theme twice. Second Section: Bar 55 begins a “ground bass”, following the pattern used by Brahms at the end of his variations:
This is heard three times, with fluid counterpoint, mostly crotchets, in four upper voices.
[539] At bar 70 this fragment begins again, though with a slightly different rhythm, but is modified after the second bar, leading to a freer development of the idea. At bar 75 it appears, in shortened form, in F minor, and at bar 82 it appears in Eb minor. From bar 87 the motif of the rising fourth is developed sequentially in the bass, with resultant modulations. The same motif is then taken up in bar 91, crescendo, in the hands with increasing chromaticism, and further tension is added by the inclusion of the dotted rhythm of the original theme in alternation with this motif.
[540] The recapitulation begins at bar 109. Although there is no dynamic indication, the massive chords used – eight to ten notes per chord – suggest fortissimo. At bar 131, a lengthy passage of further modulations occurs, with a diminuendo, and an effective use of chromatic harmony to express a change of mood, developing the opening notes of the tune, for example at bar 142:
[541] At bar 152 the theme is played by the left hand on Voix Celestes, with a soprano countermelody in the right hand, Flute 8’. A soft coda begins at bar 170. In this section there is, as we found in the soft variation of Adeste Fideles, an alternation between the root and the fifth of the tonic chord:
The piece ends ppp.
[542] The most interesting features of this improvisation are the second and third sections, the first being a fairly straightforward presentation of the theme. The idea of using the ground bass as the basis of the development is a creative move, as is the decision to break off the repetitions and move into a more fluid form of development. Equally interesting is the decision to extend the piece by a further development of the opening motif and to present the theme yet once more, this time with quite a different mood created by the use of the diminuendo and colourful harmony. We see here a mastery of form, which is very different from an imprisonment within predetermined, fixed formulae. While the overall ternary form has some parallels with the andante discussed in the chapter on symphonic forms, we find, as with the other improvisations, a re-thinking of what is needed, based on the very particular theme which was used.
[543] It is interesting to note that, while all these improvisations are based on choral tunes, none of them follow the forms developed in the treatise: contrapuntal chorale, canonic chorale, ornamented chorale, fugal chorale. There is a certain irony here: the chorale forms most often used in the Conservatoire’s exams on plainchant improvisation used forms drawn largely from the practice of J.S. Bach, while Dupré, when faced with Lutheran chorales chooses, in this instance, not to adopt any such forms.
The Language of Dupré’s Improvisations
[544] The language, especially the harmonic language, of Dupré’s improvisations is clearly more conservative than that of his compositions. It would perhaps take a much greater degree of serious study to ascertain why this is the case. Thierry Escaich, one of today’s finest organ improvisers, refers to this issue in relation to his own playing:
I came to music at a very early age by this simultaneous approach of improvisation and composition. But, the more I progressed through my childhood and teenage years, the more my personality as a composer took shape, and more a real divergence grew between my language as an improviser, who sometimes had trouble quickly integrating what the composer had elaborated for weeks and who then often took refuge in stylistic expressions from the past. It was only gradually that a certain convergence arose between these two facets of my personality.118
[545] The problem of divergence between composer and improvisor, if it is a problem, is mentioned here, and the convergence which, in Dupré’s case, was less apparent. Dupré admitted that, after his student days, he no longer worked at improvisation:
I have never practised improvisation since my school days. As regards improvising a symphony or a sonata, I tried it one day and it all came naturally, but don’t breathe a word!119
[546] Perhaps if Dupré had continued to work on his improvising skills, his improvisatory language would have kept pace with that of his compositions.
Dupré’s Improvisations and his Treatise
[547] This study has looked at a limited number of Dupré’s recorded improvisations. A more exhaustive study of all available data would, no doubt, reveal certain consistent personal approaches to improvisation not expounded in the treatise. The small number of improvisations we have reviewed do, however, already show that, while on the one hand Dupré sometimes keeps strictly to the forms given in the treatise (for example, the canonic chorale and the scholastic fugue), in many other instances he adapts and develops forms in new ways. Thus the movement ‘from rigidity to freedom’ which we have seen in the treatise, progresses towards further freedom in Dupré the improviser, who is no longer a student and who has moved beyond the treatise.
[548] This confirms an intuition that the treatise is not an abstract discourse on improvisation but a practical manual in which, from the very first page the user is referred to as ‘the student’.120 It is a student manual for developing technique and thus indicates, with directives, those exercises and work which are to be done in order to gain mastery in harmony, voice-leading, analysis, counterpoint, control of form and other skills. As such it represents a starting point and an initial trajectory for the one who would like to develop their skills, and the rigidity adopted at several turns is not an end in itself but a means towards overcoming technical difficulties. The ultimate aim is freedom of technique. There is, to be sure, more to improvisation than technique. Jean Langlais must have sensed this when, after gaining a premier prix in the Conservatoire, he turned to Charles Tournemire for further lessons. Ann Labounsky says of Tournemire that he was not concerned with technique but with the poetic elements of improvisation and that his students needed to have the firm grounding in technique that a premier prix in organ from the Conservatoire assured. Contrasting his method with that of Dupré, she says, quoting Langlais:
Above all, he insisted on poetic harmonies and sonorities, which teaching method contrasted sharply with that of Dupré: “Modulate to this key,” Dupré would say, “add stops, take off stops.” Tournemire, by contrast, was “a great poet, but not a technician. Tournemire had a superlative technique himself but did not teach technique.121
[549] One might add that if a student of Tournemire were inspired some day in an improvisation to include a canon as a poetic element, it might take the prior training of someone like Dupré to realise the dream.
