b. 6-7

composition: Op. 10 No 12, Etude in C minor

No fingering in A (→FEGE)

Fingering in EE

Fingering written into FED

..

In the main text we include the fingering written by Chopin in FED. Fontana suggested identical fingering in EE.

b. 6-7

composition: Op. 10 No 11, Etude in E♭ major

Slurs in A

FE (→GE1), interpretation

GE2 (→GE3GE4)

Our suggestion

..

The slurs of A in these bars are inaccurate, which was only partially corrected in FE (→GE1). The ambiguity was eliminated in EE and – in a different way – in subsequent GE,s, yet Chopin did not participate in their elaboration. Taking into account analogous bars 14-15, in which Chopin probably corrected the slur, and 38-39, in which he combined the slurs in A, in the main text we suggest a continuous slur from the 2nd quaver in bar 6 to the middle of bar 8.

b. 6-7

composition: Op. 10 No 6, Etude in E♭ minor

Long accents in A

Different accents in FE & EE3 (→EE4)

One accent in EE2

Short accents in GE

..

Two long accents visible in A were reproduced in FE (→EE; in EE2 the accent in bar 7 was overlooked) in varied ways. GE includes short accents in both bars. There is no reason to assume that Chopin interfered with any of the versions.

composition: Op. 10 No 7, Etude in C major

Slur in A

Slurs in FE (→GE,EE)

Slur suggested by the editors

..

Chopin added a slur in bars 7-8 at the time of proofreading FE (→GE,EE). According to us, the proofreading's goal was to extend the slur from bar 6 and the applied solution is of a simplified nature – extending a slur required much more workload of the engraver, thus Chopin could have felt embarrassed to require such a change in a place which, actually, was printed in accordance with the base text. See the remark concerning extending the slur of A in bars 2-3. Cf. bars 14-15.
