b. 22

composition: Op. 25 No 1, Etude in A♭ major

..

Many sources lack in one or both naturals before the bottom notes in the R.H. in the 1st and 2nd group of semiquavers. CDP lacks in both signs, while A (→GE1), FE and EE only the second. The correct notation is included in AI and GE2 (→GE3).

AI and EE1 lack in the  raising d2 to d2 at the beginning of the 2nd group of semiquavers.

composition: Op. 25 No 1, Etude in A♭ major

..

In CDP in the part of the L.H., the copyist wrote in these bars the version of bars 22-23, which, e.g., at the beginning of bar 24 results in juxtaposition of the A major chord in the R.H. with the C major chord in the L.H. Beyond any doubts, it is the copyist's error, yet it cannot be conclusively stated what could have been in bar 24 if it had not been for the error. We assume that it is the text which is featured in A in this place.

The different version of AI is certainly earlier. Chopin rejected it in order to – presumably – not to reveal the further direction of the modulation too early.

In some of the sources the notation of accidentals in this bar is less accurate, which, however, does not influence the clarity of the text. In A and FE, all the necessary accidentals before the lowest notes of particular groups in the R.H. and top notes in the L.H. are missing. The same probably applies also to CDP, although it is hard to conclusively state due to a serious mistake committed by the copyist in this place. The notation of AI is more precise – Chopin wrote there both naturals raising d1 to d1. In turn, the situation in EE is just the opposite – it is exactly these naturals that are missing. GE added all the necessary signs.

FE2 added a cautionary  before g1, undoubtedly justified after g1 appearing in this edition at the end of the previous bar. Similarly in EE3, where the cautionary  was added both in the R.H. and in the L.H. before g.
