b. 41

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

No  in CLI

Natural in ApFE (→GE,EE

..

Lack of the  returning b2 on the penultimate semiquaver is most probably an inaccuracy of CLI's notation. Chopin may have written the accidental already in the handwritten base text for FE.

b. 42-48

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

No fingering in Ap

Fingering in FE (→GE,EE

In the main text we give the fingering written by Chopin in FEcor. See also bar 45.

b. 42

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

Second in CLI & Ap

d3 in FE (→GE,EE

..

The second in CLI and Ap is the original version, compatible with the general texture scheme of the Etude, in which the chromatic passages in the upper voice are accompanied with two-note chords. In the main text we give the version introduced in FEcor (→FEGE,EE). Chopin had already introduced a similar change in analogous bar 15, both in Ap and in the base text for FE.

Our suggestion

..

In the version prepared for printing Chopin did not use the dynamic hairpins he wrote in Ap (also in the next bar). In one of the last proofreadings of FE (→GE,EE) he, however, added a verbal indication. In the main text we suggest to extend the marked range of the indication, as there is no doubt that crescendo leads to  in bar 43.
