b. 6-7

composition: Op. 10 No 1, Etude in C major

..

The sharp in front of fin bar 6 is present only in EE, while the  in front of ain bar 7 appears only in the later impressions and editions (EE4 and all GE,s except for GE1). Moreover, in CLI there is no  in front of f1 in bar 6. Those discrepancies does not influence the reading of the text, yet they result from the gradually specified rules governing the accidentals.

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.

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.
