b. 41

composition: Op. 25 No 9, Etude in G♭ major

in GC (→GE) & EE

No indication in FE

..

In GC, the leggierissimo indication replaced the earlier written . A similar addition was added probably by Chopin in the base text to EE. In FE, the correction was either overlooked, if there was no , or unfinished, if it was there.

b. 43

composition: Op. 25 No 9, Etude in G♭ major

..

In GC (→GE1), FE and EE1, before the last octave in the R.H. (c3-c4) there are flats. The signs, completely unjustified in this place, must have been also in [A], which is a very meaningful example of Chopin's uncertainty concerning the issue of the prevailing set of key signatures, particularly the last one. The signs were removed in GE2 (→GE3) and EE2, while in GE3 they were reintroduced, which indicates rather a mechanical work of the reviser of EE3, copying the versions of GE1 without having analysed their accuracy.

No fingering in EE1

6 digits in GE2

In the main text we give the complementary fingering of GC (→GE1) and FE and EE, although it is possible that it was only the latter that was given by Chopin, as the copyist, having in front of him these four numerals, could have mistaken the figures and, after having correctly written the first two ones, could have added the last three four semiquavers further. In GE2, the third numeral was added in bar 45, whereas in GE3, the alleged return to the version of GE1 can be a result of the blurry imprint of this numeral.

Slur in GC (→GE) & FE

Slur in EE

..

The shorter slur of EE is probably inaccurate.
