b. 33-34

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

a1-g1-g1 in AI

f1-f1-e1 in A (→CDP,GE), FE & EE

..

In the original version, written in AI, the bottom notes of the figuration in the R.H. double the melodic line from the middle of bar 33  – a1-g1-g1. in A, Chopin immediately wrote the changed version, also in the L.H. where on the 4th beat in bar 33 and 1st beat in bar 34 there are two ginstead of d1 and e1 as the top notes. Interestingly enough, the final edition of the part of the R.H. in the 2nd half of bar 33 was initially written in AI, yet it was changed there. Hence we could talk about Chopin's hesitation here. Cf. the note to bars 32-33.

b. 33

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

e in AI, A (→CDP,GE), FE & EE2 (→EE3)

in EE1

..

The version of EE1 is most probably a mistake (the so-called Terzverschreibung), corrected in EE2 (→EE3).

b. 33

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

..

The flat raising d2 to d2 was added only in EE2 (→EE3) and GE2 (→GE3). There is no doubt that Chopin committed a mistake here, in face of the  before d1 in the L.H.

b. 35

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

..

In AI it can be seen that it was the one octave lower E that was the original bass note on the 1st and 3rd beat of the bar.

b. 35

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

g1 in AI, A (→CDP,GE), FE2 & EE

b1 in FE

..

The version of FE1 is certainly a mistake, corrected in FE2. Although in A one can see the identical correction – a deleted b1 and added g1 – yet a more profound analysis of the notation reveals that it is only the most visible part of a greater proofreading, including the last 5 semiquavers in the R.H., as Chopin wrote here the figure appearing at the end of bars 37 and 39 by mistake.
