Both in GC and FE one can see traces of corrections from  to . EE also features the final version. Cf. the Etude in A minor, No. 11, bars 5 and 13.

b. 5-6

composition: Op. 25 No 10, Etude in B minor

Short accents in GC (→GE)

Long accents in FE & EE

..

The accents in GC (→GE) do not show varied features in these bars and are shorter than, e.g., the ones in GC in bars 9-10. In turn, in FE, and particularly in EE, the first five signs are clearly longer than the sixth one. It is hard to determine how this difference occurred and, as a consequence, what was Chopin's intention in this regard. Therefore, in the main text we reproduce the notation of the basic source, i.e. GC. See also bars 107-108.

The sharps returning f1 and F on the 3rd beat of the bar are present only in GE2 (→GE3). A similar mistake appears in bar 108.

b. 7-10

Long accents in GC & EE

Different accents in FE

Short accents in GE

..

Three out of four accents in GC are undoubtedly long accents, the fourth one (in bar 8) may be interpreted as either long or short. In GE they were reproduced as short. EE includes distinct long accents in all these bars, FE – only in bars 9-10, yet the one in bar 7 may also be considered as long. Therefore, it seems that the use of long accents by Chopin is much more likely here.

b. 7-8

composition: Op. 25 No 10, Etude in B minor

In the 2nd half of the bar the sources repeat the sharps before A1-A and a-a1. In the main text we delete the unnecessary signs.
