b. 2-11

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

No a in A

a in FE (→GE)

a & fingering in EE

..

Chopin changed the version of the last semiquaver in bars 2 and 10 written in A while he was proofreading FE (→GE,EE). Traces of this proofreading are clearly visible in both bars. What is interesting is the fact that in bar 2 A had initially another version, in which a was probably involved, although without the tie sustaining it to the next bar.

In bar 2 the added note a was provided in EE with a fingering digit '3'. We include it in the main text instead of the identical direction at the beginning of the next bar.

b. 2-10

In bars 2 and 10 we add cautionary flats before a. The addition was already performed in GE2 and later GE,s and in EE4.

b. 2-3

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

Slurs in A

No slurs in FE (→GE,EE)

..

The inaccurate and unclear slurs of A were ignored in FE (→GE,EE). Their range, particularly in the case of bar 3, is uncertain. We do not include them in the main text, as Chopin did not repeat them in A and in analogous bars 10-11 and 42-43, nor did he add them in a proofreading of FE (cf. bars 47-49).
