b. 21

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

No marking in CLIFE (→GE,EE

in Ap

..

 visible in Ap may be considered as detailing the notation of FE (→GE,EE), indicating the starting point of the second crescendo wave. However, as the indications do not specify the absolute dynamic level in this place, it is quite probable that the second part of the progression was supposed to begin in meno piano, according to Chopin's intention.

In CLI and Ap there are no cautionary naturals before bass notes at the beginning of bars 21 and 23: before in CLI and before and in Ap.

The octave chords in Ap constitute, as it seems, only a transitional modification of the initial concept of seventh chords. Cf. bars 23-24.

We add a cautionary  before on the 2nd beat of the bar. The addition was already made in GE3 (→GE4GE5).

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

..

In CLI there are no essential accidentals in the part of the R.H., some of them were also omitted in the base text for FE. In subsequent proofings of FE Chopin, however, added all of them, so final FE (→EE) does not include any errors in this scope. Ap also has a totally correct notation. Lack of the  returning g2 at the end of bar 21 in GE1 probably means that Chopin added it only in the last proofreading of FE. The sign was added in GE2 (→GE3) together with few others, reminding; the majority of the latter were then removed in GE4 (→GE5), while one was added in EE4. We discuss the 2nd half of bar 22 in a separate entry due to the enharmonic difference in the notation of the 10th semiquaver.
