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 (→GE3→GE4), while the first of them also in EE4.

b. 7-8

No fingering in A (→FE→GE)

Fingering in EE

The fingering added by Fontana in EE naturally follows from the figurations.

Crotchets in A

Quavers in FE (→GE,EE)
..

Lack of extensions of c1 and b in FE (→GE,EE), written in A in bars 7 and 8, is most probably an oversight of the engraver.
