b. 65-67

composition: Op. 10 No 9, Etude in F minor

No fingering in AI & A (→FEGE)

Fingering in EE

Fingering written in FED

..

In the main text we consider the fingering of the L.H., added by Chopin in FED. In EE Fontana added the fingering both in the right and L.H. The latter is partially compatible with Chopin's entry in a pupil's copy.

Omission of the  mark at the end of the pieces is characteristic for Chopin's pedalling and is featured in numerous works, e.g., in the Etudes in C major, No. 1, C minor, No. 4, C major, No. 7, F major, No. 8, E major, No. 11. The revisers of GE and EE considered it as an inaccuracy of notation of FE.
