b. 6-8

composition: Op. 10 No 10, Etude in A♭ major

..

The cautionary  before e2 at the beginning of bar 6 was added in a proofreading of FE (→GE,EE). In the main text we still add a few cautionary signs in bar 8 – flats before a2 on the 3rd and a1 on the 5th quavers, as well as a  before f2 on the 6th quaver. The flats were already added in GE2 (→GE3GE4), while the first of them also in EE4.

Versions in AI

Version in A (→FEGE,EE)

..

At the time of writing AI, Chopin was still looking for the best melodic continuation for the first, five-bar-long phrase. In the 1st half of the bar, after numerous deletions, he wrote two versions, out of which it was eventually the second one that was adopted, marked in this manuscript as ossia. The only version of the 2nd half of the bar was then changed in A.
