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

f1 in AI, A (→GE), FE & EE

e1 in CDP
..

The version of #CFP, although possible from the harmonic point of view, is most probably simply a mistake.

In A and the remaining sources, the a note, present in AI as the highest note of the 1st figure in the L.H., was replaced by d1. Only in FE the note is not provided with a cautionary flat.

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

e in CDP

d in AI, A (→GE), FE & EE
..

The version of CDP results in a pianistically uncomfortable cluster of three e notes, played alternately by the right and left hand. Therefore, it is most probably a mistake – the copyist did not notice the difference between the third and fourth figure in this bar and marked the latter as repetition of the previous one. He committed a similar and undeniable, yet more serious, mistake also at the very beginning of the Etude.

A in CDP

A1 in AI, A (→GE), FE & EE
..

The version of CDP is probably erroneous (the copyist could have looked at bar 10 in A), as the A1 note is already present in AI and it is highly unlikely that Chopin would have then returned to the probably original version with A – cf. bar 1. However, if CDP is a copy of another, lost autograph, allegedly intended for gift, it cannot be excluded that the version was written there by Chopin.

b. 13

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

..

In AI one can see a pencilled correction – d written in ink (the 1st note in the bar) was changed to D.
