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.

Rhythm in A, interpretation

FE (→GE,EE)

..

In bars 41 and 43 A has the original version of the rhythm, corrected by Chopin in FE (→GE,EE). Moreover, in bar 41 the notation of A is erroneous, as there are no dots next to the crotchet on the 2nd quaver in the bar extending its value.
