b. 8

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

..

In A there is no  returning don the penultimate semiquaver in the R.H. The natural next to the subsequent note proves that Chopin forgot about the existence of d1 at the beginning of the bar. The sign was added in a proofreading of FE (→GE,EE).

 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

Lack of the tie sustaining a in A is most probably a mistake, which is confirmed by the tie added by Chopin in a proofreading of FE (→GE,EE).
