7 The slippage in her article between scholarly methodologies and regulative concepts is also problematic. She elevates new musicological approaches that stress compositions’ connection to culture by downplaying the existence and importance of a pervasive concept of absolute music manifested as abstract autonomous art music. Yet a pervasive concept of absolute music need not preclude new methodological ways of studying music.

8 Massow, for instance, notes: ‘F. Busoni proceeds, on the other hand, in his Sketch of a New Aesthetic of Music (Leipzig, 1916), to define absolute music principally in contrast to formalism’ (‘F. Busoni wendet sich wiederum in seinem Entwurf einer neuen Ästhetik d. Tonkunst (Lpz. 1916) prinzipiell dagegen, absolute Musik unter dem Aspekt des Formalen zu definieren’).

16 Tonkunst has a slightly different meaning from Musik, and was Busoni's chosen term in the title of his Sketch. Since there is no direct English equivalent of the term, I have chosen to retain Busoni's original here. Tonkunst refers to tone art, or the craftmanship of tones (composition), as opposed to the more general notion of music as natural tones not subjected to human creativity.

19 ‘Die Musik, die in der ästhetischen Umgangssprache “absolute” genannt wird, verdient nach Busoni den Namen nicht, einen Namen, der auf das “sinnliche Scheinen” des “Absoluten” in einer losgelösten, fessellosen Musik zielt. […] Busoni proklamiert eine “freie” Musik, losgelöst von überlieferten Formen und insofern “absolute”.’ Carl Dahlhaus, Die Idee der absoluten Musik (Kassel, 1978), 43 (trans. Erinn E. Knyt).

23 Busoni did not want the music to narrate a story or plot, as it does in Strauss's Don Quixote, for instance. He did not like pieces in which the music had to follow a storyline – the fight with windmills, Sancho Panza falling off his donkey, etc. – but he did not mind if a dramatic plot suggested combinations of more abstract structures.

Pfitzner wrote his pamphlet entitled ‘Futuristengefahr’ (‘Danger of Futurists’) largely in response to the 1916 version of Busoni's Sketch. Busoni published this open letter as a public reply to Pfitzner's attack: ‘Offener Brief ’, Vossische Zeitung, 3 June 1917, repr. in Ferruccio Busoni, Von der Einheit der Musik: Von Dritteltönen und Junger Klassizität von Bühnen und Bauten und anschliessenden Bezirken, ed. with commentary by Martina Weindel, Quellenkataloge zur Musikgeschichte, 36 (Wilhelmshaven, 2006), 87.

36 Busoni, ‘How I Compose’, The Essence and Oneness of Music and Other Papers, trans. Ley, 50–1. This essay originally appeared as ‘Wie ich komponiere?’, Der Konzertsaal (Berlin, May 1907), repr. in Busoni, Von der Einheit der Musik, ed. Weindel, 33. Die Brautwahl (The Bride Choice) was premièred in Hamburg in 1912.

37 Busoni published several versions of this composition (scored for one and two pianos). He also intended to score the piece for orchestra, but never completed the project. The first solo-piano version appeared in 1910. A second and shorter minore solo-piano version was published in 1912, and a version scored for two pianos appeared in 1922. All versions were originally published by Breitkopf & Härtel.

38 An analysis of the music shows that Busoni's diagram was not drawn to scale, if one were to equate architectural space to page-length. The opening section (marked as no. 1) occupies 21 of the 66 pages, or approximately 30% of the total page-length of the composition. Yet in the diagram, it appears to represent less than a twelfth of the total space of the building. A breakdown of the page-lengths of each section in the most recent edition by Breitkopf & Härtel is as follows:

1. 1.

   1. Choral Introduction, pp. 3–23

2. 2–4.

   2–4. Fugues 1–3, pp. 23–43

3. 5.

   5. Intermezzo, pp. 44–5

4. 6–8.

   6–8. Variations 1–3, pp. 46–54

5. 9.

   9. Cadenza, pp. 55–7

6. 10.

   10. Fugue 4, pp. 58–62

7. 11–12.

   11–12. Chorale and Stretta, pp. 63–8.

In Busoni's diagram, the amount of space allocated to each section therefore probably represents importance, rather than length. The fourth fugue is only five pages long, but is given substantially more space in the diagram than the first three fugues, which together occupy 21 pages. The fourth fugue is the most radical in conception and key. Its opening in B♭ minor is much more tonally remote in relation to the opening G major/minor choral introduction than the D minor centre of fugues 1–3. Moreover, Busoni's treatment of the subjects in fugue 4 is his own, rather than a transcription of Bach's music, as is the case with fugues 1–3. It is the climax that arrives after developmental variations and a cadenza.

41 It is possible that Busoni could also be simultaneously drawing upon Friedrich Nietzsche's use of the term to refer to unconventional form in Wagner's music. Busoni admired Nietzsche's writings and was thoroughly acquainted with them.

56 Interestingly enough, in the English translation it initially appears that Busoni describes that opera as ‘absolute’. However, in the original German, the term ‘schlechtweg’ appears instead of ‘absolute’. A more accurate rendering would probably be ‘opera par excellence’ or ‘the epitome of opera’. Although not of terminological relevance for this article, the passage still provides an example of the type of opera that Busoni was idealizing.

57 Busoni, Sketch, trans. Baker, 9.

58 The English translation uses the term ‘Classicism’, which is slightly less accurate than ‘Classicality’.

59 Busoni, ‘Young Classicism’, 20. Because of Busoni's non-linear notion of time, old and new compositions could be combined irrespective of style or musical language: audible quotations from Bach's tonal music could appear alongside newer experimental writing by Busoni. This is evident in such pieces as the Fantasia nach Bach or the Fantasia contrappuntistica. This differs from Stravinsky's neoclassical writing, which is more consistently atonal throughout.

60 The elegies were composed in 1907, but first published in 1908.

61 The middle tarantella-like section material is borrowed from Busoni's Piano Concerto (1904).

62 Halm, however, idealized instrumental music as the epitome of the absolute. In his 1928 essay ‘Programmusik und absolute Musik’, he praised Bruckner's symphonies as the epitome of absolute music. He especially liked the first movement of the Ninth Symphony, where the best of Bach and Beethoven, of features of fugal and sonata form, were united. August Halm, ‘Programmusik und absolute Musik’, Der Kunstwart, 42 (1928–9), 147–52.
