Pitch

b. 2-6

composition: Op. 10 No 2, Etude in A minor

Triad & fifth in CLI

Triads in Ap & FE (→GE,EE)

..

The fifth on the 3rd beat of bars 2 and 6 in CLI is probably the original version. The c1 notes were originally absent also in FE, as in both bars Chopin added them in FEcor. Chopin hesitated in which places to put the cautionary naturals before c1, which can already be seen in FEcor, where before the triad on the 2nd beat of bar 2, a  was written and then deleted. Eventually, FE (→EE2EE3) has a sign before the triad on the 3rd beat of the bar, which we adopt to the main text in all analogous bars. GE1 (→GE1a) has a  before the 1st triad in both bars, while in the later editions arbitrary additions were also performed in this respect.

b. 2

composition: Op. 10 No 2, Etude in A minor

..

In the middle of the bar in FEcor there is no  raising c3 into c3. This obvious mistake was corrected by Chopin in one of the later proofreadings.

Our suggestion

..

In bars 2 and 6 in one of the last proofreadings of FE (→GE,EE) cautionary naturals before c2 in the chord at the end of the bar were added. According to us, accidentals in those places are actually unjustified, yet due to their probable authenticity, we suggest to consider the first of them.

b. 2-6

composition: Op. 10 No 2, Etude in A minor

No  in CLI

Naturals in ApFE (→GE,EE

..

Lack of the  returning b2 on the penultimate semiquaver in bars 2 and 6 is most probably an inaccuracy of the notation of CLI. In bar 2 Chopin added the sign in FEcor, in bar 6 – probably already in the handwritten base text for FE.
