b. 24-26

Quite a significant difference in the range of the diminuendo indication suggests that it was written by Chopin in GC and base text to EE independently. The earlier ending of the dashes determining the range of this indication in GE1 is probably a result of an inaccurate interpretation of GC and perhaps also difficulties with finding place for some of them.

b. 24

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

b1 in GC (→GE)

g1 in FE & EE

..

The version of GC (→GE) is almost certainly erroneous – the copyist could have copied it only from one of the remaining Stichvorlage manuscripts, and it is absent both in FE and EE.

No slurs in GC (→GE1), FE & EE

Two slurs in GE2 (→GE3)

Slurs suggested by the editors

..

The missing slurs in the majority of the sources must be considered as Chopin's oversight. We suggest slurs used in analogous bars 7-8. An identical addition was introduced already in GE2 (→GE3).

..
