b. 8

composition: Op. 10 No 4, Etude in C♯ minor

 in AI

4 accents &  in FE (→EE)

3 accents &  in GE

Our alternative suggestion

..

The indications of AI were changed in the version prepared for print, certainly with the participation of Chopin. Therefore, in the main text we give the version of FE (→EE). However, some of its elements can raise certain doubts, particularly the  hairpins and the last accent, overlooked in GE. Therefore, we alternatively suggest a certain interpretation of the notation of FE, based on an assumption of an inaccurate reproduction of Chopin's intention by the engraver.

b. 9-10

composition: Op. 10 No 4, Etude in C♯ minor

Slurs in AI, contextual interpretation

Slurs in FE (→GE,EE)

..

It is possible that at the time of writing AI, Chopin considered the slurs in bar 9 as valid also later, in bars 10-11. In the main text we give the later and fuller slurring of FE (→GE,EE).

 in bar 9 in EE

..

The hairpins of AI, leading to  in bar 11, is an earlier concept of dynamic indications. In the main text we stick to the version of FE, reproduced with minor inaccuracies also in GE and EE.
