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. 8

composition: Op. 25 No 1, Etude in A♭ major

e in CDP

d in AI, A (→GE), FE & EE

..

The version of CDP results in a pianistically uncomfortable cluster of three e notes, played alternately by the right and left hand. Therefore, it is most probably a mistake – the copyist did not notice the difference between the third and fourth figure in this bar and marked the latter as repetition of the previous one. He committed a similar and undeniable, yet more serious, mistake also at the very beginning of the Etude
