b. 19-28

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

Fingering numeral in Ap

Fingering in FE (→GE,EE

..

In the main text we give the fingering written by Chopin in FEcor. FE (→GE,EE) reproduced it with small imprecision, commented separately: '2' was omitted at the beginning of bar 20 and three digits in bars 25 and 26. In these bars Ap has only one fingering digit, '1' at the end of bar 26.

b. 19-23

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

 in Ap

poco a poco cresc. in FE (→GE,EE

..

It is unclear whether poco a poco cresc. given in the main text twice – after FE (→GE,EE) – is supposed to be understood as two waves of a dynamic build-up or only one. The repetition of the indication may have just resulted from the fact that in FE a new page begins in bar 21 (cf. the remark concerning bars 19-21). However, the dynamic markings of Ap – particularly the repeated  in bar 21 – advocate for two waves.
In this place, as an alternative to the indications of the printed version, we give only these indications of Ap, which are totally incompatible with them. The remaining ones are discussed in the remarks concerning bars 19-23, 20-22 and 21.

b. 19-23

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

  in Ap

No signs in FE (→GE,EE

..

The pairs of hairpins in bars 19, 21 and 23 visible in Ap are not contrary to the general crescendo, as they mainly concern the melodic line. The meaning of short  signs is unclear (cf. bars 20-22); according to us, they should be interpreted here as diminuendos matching the preceding them crescendos. We do not consider them in the main text.

b. 20

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

in CLI, Ap & FE (→GE)

in EE

..

in EE is most probably the engraver's mistake, yet lack of correction even in EE4 indicates a possible revision (by Fontana?).
