b. 5

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

The Allegro con brio indication in GC is written with Chopin's hand. It can also be seen that Chopin deleted Allegro molto con fuoco written by the copyist. In this case the composer ensured that the final version is in all sources.

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.
