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 (→FE→GE,EE). Chopin had already introduced a similar change in analogous bar 15, both in Ap and in the base text for FE.

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

Triad in CLI & Ap

Sixthin FE (→GE,EE) 
..

The triads in CLI and Ap are the original version, which is confirmed by the fact that Chopin deleted the inner note in FEcor. What is conspicuous is that the note was an e3, which probably originally appeared in CLI (it was then corrected to f3).

D in CLI

D-d in Ap & FE (→GE,EE) 
..

The single crotchet in CLI is undoubtedly the original version. In Ap and FE (→GE,EE) Chopin took the decision to insert a quaver octave here (in analogous bar 17 a single D was left), which may have been related to an increased sound volume in the last section of the Etude. Cf. a further remark in this bar.

b1 & b in CLI

b1, b1 & b in FEcor 

b1 & b in Ap & FE (→GE,EE) 
..

The version of CLI without the Neapolitan chord was changed by Chopin in Ap, yet not in the base text for FE (differently as in analogous bar 17). Only in FEcor Chopin added the flats lowering b to b and b1 to b1, yet both accidentals were put on the 2nd beat of the bar, as if b1 was still supposed to be in the 1st chord. It was probably a mistake, as in one of the subsequent proofreadings Chopin added a  also at the beginning of the bar (the unnecessary  on the 2nd beat of the bar was removed only in GE3 and subsequent GE,s).

Fifth in CLI & FE (→GE,EE) 

e in Ap
..

The single e crotchet in Ap is probably a later version than the e-h fifth in CLI. However, Chopin conserved the fifth in the base text for FE and confirmed his decision by adding in FEcor a  returning b in this place. See a previous remark in this bar.
