b. 22

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

e in CLIFE (→GE,EE

d in Ap

..

In Ap Chopin marked the enharmonic change of the bass note in the last chord, however, eventually he returned to the original concept in FE (→GE,EE). Cf. bar 20.

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

f1-c2 in CLI

c2 in ApFE (→GE,EE

..

The additional f1 in CLI is certainly the original version, Chopin waived this note in both Ap and in the base text for FE. Cf. bars 20 and 24.

b. 22

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

..

In CLI the 10th semiquaver is written as an a2, which constitutes a natural cause of changes in the notation of the accidentals appearing in the further part of the bar. Lack of the  returning g2 on the penultimate semiquaver is, however, a patent error. In the majority of sources there is a reminding (?)  before the last note in the bar – only Ap and GE4 (→GE5) omit this rather unnecessary sign.

d1 &  before b in FE (→GE,EE

..

Similarly as two bars before, Ap features chords with the span of an octave on the 2nd beat of these bars. In the main text we give the chords with the span of a seventh present in the remaining sources.

In bar 23 there is no cautionary  before b.
