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 d
1 to d1 on the 2nd semiquaver in bar 34 in A (→FE1→GE,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.
