b. 31

composition: Op. 10 No 5, Etude in G♭ major

d3 in A, FED, FEJ & FES

b2 in FE (→GE,EE)

..

b2 as the 5th note in FE (→GE,EE) is certainly a mistake of the engraver. The accuracy of the version with dwritten in A is confirmed with entries in all pupils' copies.

composition: Op. 10 No 5, Etude in G♭ major

e1 in chords in A

No e1 in FE (→GE,EE)

..

The chords in A have an additional enote, which was however deleted by Chopin in a proofreading of FE (→GE,EE). The chords were also corrected by Chopin in a similar motif four bars later.

b. 38-39

composition: Op. 10 No 5, Etude in G♭ major

e1 in chords in A

c1 in FE (→GE,EE)

..

The version of A with e1 is obviously earlier, therefore, in the main text we give the corrected by Chopin text of FE (→GE,EE). Cf. bars 34-35.
