Issues : Errors of GC

b. 108

composition: Op. 25 No 10, Etude in B minor

Octave in GC (→GE1)

Chord in FE, EE & GE2 (→GE3)

..

Lack of the middle note on the 3rd beat of the bar is almost certainly a mistake of GC (→GE1).
In FE the note is present, yet there is no  returning F. EE and GE2 (→GE3) have the correct text.

GC does not have a quaver flag here, which is most probably an error of the copyist.

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

In GC the second quaver in the R.H. is written too low in all of these bars, so it could be interpreted as an or F. The respective notes in the L.H. allow to guess the correct text, although in bar 113, the note in the L.H. is also written incorrectly as an A1. The remaining sources – including GE, based on GC – feature the correct text.

b. 112

composition: Op. 35, Sonata in B♭ minor, Mvt II

..

There are no accidentals before the chord on the L.H. on the 2nd beat of the bar in GC and FE (→EE1). The necessary  raising c1 to c1 was added in GE and EE2. In the main text we add a cautionary  before e1.

b. 113

composition: Op. 25 No 10, Etude in B minor

..

In GC (→GE1) and EE, there are no accidentals before the crotchets, so they should read as c and c2. In spite of the fact that the version does not raise any doubts as far as the sound is concerned, the omission of the naturals is proved by:

  • the logic of harmony – this and the previous triplet create an abbreviated version of the motif used in the progression in bars 109-112. In this abbreviated version it is then repeated twice in the further part of bars 113-114. There is no reason to resign from the semi-tone movement of crotchets filling the octaves in one place only;
  • misleading chromatic orthography – change from d to c despite preserving regular notation of the octaves in the F minor key;
  • signs added – probably by Chopin – in the proofreading of FE.
