Numbering of the piano sonatas
For the piano Sonatas, there is no uniform numbering system. There are several reasons for this, including that there is no consensus regarding the inclusion of independent movements as being part of incomplete or unfinished sonatas. This issue has proven to be troubling to scholars and performers of the works, who have to decide which of these movements, if any at all, should be included for a certain sonata. In some instances, it is also necessary to determine the order in which they are to be presented.
A common numbering system, found on recordings and some websites has 21 sonatas: [3]
- D 157
- D 279 ('Unfinished')
- D 459
- D 537, Op. posth. 164
- D 557
- D 566
- D 567
- D 571 (fragment; including various other mvmts.)
- D 575, Op. posth. 147
- D 613 (fragment)
- D 625
- D 655 (fragment)
- D 664, Op. 120
- D 784, Op. posth. 143
- D 840 ('Relique')
- D 845, Op. 42
- D 850, Op. 53 ('Gasteiner')
- D 894, Op. 78 ('Fantasy')
- D 958
- D 959
- D 960
Unnumbered editions
The following two editions of Schubert's piano sonatas are incomplete and abstain from providing a numbering system:
- Edition Peters – Sonaten für Klavier zu 2 Handen (Leipzig: C.F. Peters, 1970-1974): an edition in two volumes that includes eleven complete sonatas (D 537, D 568 2nd version, D 575, D 664, D 784, D 845, D 850, D 894, D 958, D 959, D 960)
- Schirmer Edition – Ten sonatas for pianoforte (New York: G. Schirmer, 1906): an edition in one volume that includes ten complete sonatas (D 537, D 568 2nd version, D 575, D 664, D 784, D 845, D 850, D 958, D 959, D 960)
The following edition of Schubert's piano sonatas is complete, but abstains from providing a numbering system:
- G. Henle Verlag – Klaviersonaten (München: G. Henle, 1979-1989): an urtext edition in three volumes that includes all complete sonatas, all unfinished sonatas, and all independent movements generally associated with these unfinished works (D 154, D 157, D 279/346/(277A), D 459/459A, D 537, D 557, D 566/506, D 568 1st and 2nd versions, D 571/604/570, D 575, D 613/612, D 625/505, D 655, D 664, D 769A, D 784, D 840, D 845, D 850, D 894, D 958, D 959, D 960) . Volumes I and II were edited by Paul Mies and fingered by Hans-Martin Theopold. Volume III was edited and fingered by Paul Badura-Skoda. It includes all unfinished sonatas and the independent movements associated with them, with completions by Badura-Skoda of all fragments with the exception of D 154, D 655 and D 769A. While the sonatas in this last volume carry a numbering of 1-10, this is not a numbering system of the entire sonata output, given that the first two volumes assign numbers 1-11 to the works they contain.
Numbered editions
