b. 5-12

composition: Op. 25 No 11, Etude in A minor

..

In GC – undoubtedly in accordance with [A] – bars 5-14 are provided with numbers 1-10 as model for the briefly written bars 69-78.

b. 5

composition: Op. 25 No 11, Etude in A minor

..

GC (→GE1) features naturals before b3 and a3 in the 3rd group of semiquavers. These unnecessary signs are remnants of the erroneously repeated 2nd group of semiquavers in this place. The mistake was corrected, by changing only the elements influencing the correctness of the text – pitch of the notes,  to  before the 3rd note. In GE2 (→GE3) the naturals were already not included.

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.

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.

b. 5-8

composition: Op. 25 No 5, Etude in E minor

..

We add cautionary naturals before g1 in bar 5 and before the first c2 in bar 6. The signs were added already in GE3, together with the naturals before a2 and c2 at the beginning of bar 8.
