b. 8

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

cresc. in A

FE (→GE,EE)

..

In the main text we put cresc. over the part of the R.H., in accordance with A. In the editions it was placed between the staves, which in this case makes no big difference, as the part of the L.H. is also to be performed crescendo

b. 8

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

 in A

Two signs in FE (→EE)

 in GE

..

The additional  sign, placed in FE (→EE) between the staves, seems to be added during a proofreading, thus correct. The hairpins could refer to the R.H., which would cause problems (crescendo on a long note), or to the left one, where they would double the sign placed under the semiquavers. Due to this fact, we think that the most likely explanation is the following: the sign put in A under the semiquavers in the L.H. was erroneously reproduced in FE over them. In the last proofreading of FE (not included in GE) Chopin added the second  under the L.H., confirming his intention of providing the progression of semiquavers with this sign. Therefore, in the main text we give only the hairpins of A

b. 8-9

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

No fingering in A (→FEGE)

Fingering in EE

..

The fingering of the R.H. added by Fontana in EE seems to be accurate, although it is not the only possibility and it does not arise from Chopin's fingering.

Literal reading of slur in A (→FEGE,EE)

Interpretation of A suggested by the editors

..

The slur of A in the 2nd half of bar 8 may suggest a continuation in the next bar, in which there is no possible ending of the mark.
