b. 38

composition: Op. 10 No 10, Etude in A♭ major

..

The last note of the 1st half of the bar (b) was corrected in A, while the effect of these changes turned out to be unclear for the engraver of FE who found there c1. The mistake was corrected both in GE and EE.

b. 42-43

composition: Op. 10 No 10, Etude in A♭ major

No pedalling in A

 in FE (→GE1)

  in GE2 (→GE3GE4) & EE

Our suggestion

..

Lack of the pedal release mark depressed in the middle of bar 42 must be considered as the notation's inaccuracy in this context. The  mark was added in EE and GE2 (→GE3GE4) at the end of bar 42, which is undoubtedly justified with similar indications in the previous bars. We suggest a completion after the notation of A at the beginning of bar 44.

b. 52-53

composition: Op. 10 No 10, Etude in A♭ major

Tie in A, GE & EE

No tie in FE

..

Same as in bars 50-51, we consider the omission of the tie by the engraver of FE to be more plausible than Chopin's possible proofreading of FE. However, in this place a tie was added both in GE and EE.

In FE (→EE) the double flat was erroneously placed before the bottom note of the third. However, this patent inaccuracy was corrected only in GE.
