b. 32

composition: Op. 10 No 3, Etude in E major

b-c1 in AI, A, FE2, GE, EE

c1-d1 in FE1

..

The c1-d1 second at the 5th semiquaver in the bar is almost certainly a mistake of FE1, corrected in FE2. The change to b-c1 was introduced also in GE and EE, perhaps on the basis of analogy with bar 36.

b. 32

composition: Op. 10 No 3, Etude in E major

..

The notation of accidentals is inaccurate in some of the sources, which, however, does not create any problems in interpreting Chopin's intention. It concerns mostly AI, yet in A (→FEEE2EE3) there is also no  before g2 in the L.H. (in bar 33).

b. 33

composition: Op. 10 No 3, Etude in E major

c2-e2 in AI, A & GE

b1-c2 in FE (→EE)

..

The c2-e2 third in AI and A is the original version, most probably left by inattention – the traces of similar corrections, e.g. on the 5th semiquaver of the previous bar, are visible both in AI and A. Chopin changed it in the last proofreading of FE (→EE), not included in GE.

b. 34

composition: Op. 10 No 3, Etude in E major

No f semiquaver in AI

f on second semiquaver in A (→FEGE,EE)

..

The version of AI, without the 2nd semiquaver in the bar (f), is undoubtedly earlier.

b. 34

composition: Op. 10 No 3, Etude in E major

d2 in AI & A (→FEEE2EE3)

d2 in GE & EE4

The sound of d2 at the beginning of the bar does not raise any doubts both in the autographs and in FE and EE2 (→EE3). Lack of the  lowering d1 to d1 on the 2nd semiquaver in bar 34 in A (→FE1GE,EE) is an obvious oversight of Chopin (in the manuscripts and first editions of his pieces, we find hundreds of similar inaccuracies). However, the mistake was corrected only in FE2, as the problem of incompliance of d2 at the beginning of the bar and d1 on the 2nd semiquaver was solved by the engraver of GE by deleting the  before d2. The erroneous version with d2 and d1 was introduced – most probably under the influence of GE – also in EE4. One has to underline once again that both autographs – in spite of inaccurate notation – are completely unanimous, as far as the use of the B minor, and not B major, chord is concerned; this version is then confirmed by both a proofreading of FE2 and pupils' copies, bearing numerous signs of working on the Etude with Chopin.
