b. 2

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

 in Ap

No sign in FE (→GE,EE)

..

The  sign in Ap appears in this place only in this bar. In the printed version Chopin used dynamic hairpins much less frequently. Cf. bars 10 and 14.

Octaves in CLIFE (→GE,EE

Only A in Ap

..

Lack of the lower octave at the beginning of bars 2 and 6 in Ap suggests Chopin's hesitation concerning its presence – the octaves are both in CLI, representing the earliest stage of the Etude's notation and in FE (→GE,EE), which ends the shaping process of the piece's text. Similarly in bar 10, 14, 37 and 41.

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

CLI has mistakenly cas the 8th semiquaver. A similar mistake in CLI occurs also in bars 10 and 14.

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.
