b. 25

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

No '1' in CLI, ApFE (→GE,EE

Fingering numeral in FEcor

..

The fingering digit for the lower voice, despite having been written by Chopin in FEcor, does not appear in FE (→GE,EE). It is probably a result of the engraver's inaccuracy.

b. 25-26

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

No slurs in CLIFE (→GE,EE

Slurs in Ap, interpretation

..

We do not include the whole-bar-long slurs of Ap in the main text, being faithful to the version prepared by Chopin for printing. The second of the slurs is most probably miswritten (moved to the left).

The additional c3 notes, visible in CLI and Ap at the beginning of these bars in the lower voice, were deleted by Chopin in FEcor. In FE in bar 25 a  was left before the empty space after the deleted note, which the reviser of GE moved before f3.

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

..

In FE, before the empty space after the deleted c3 note, a  was inserted, which was moved by the reviser of GE before f3. In EE2 (→EE3) the sign was removed, yet in EE4 was added before f3, probably after noticing it in GE.
