b. 75

composition: Op. 10 No 1, Etude in C major

B in CLI

C in FE (→GE,EE

..

The first note of the 2nd group of semiquavers in CLI is b1, similarly as in the 4th group there is a b3. The head of the note opening the 3rd group is illegible, but both the length of the stem and the figuration's logic indicate on b2 as the intended pitch of the note. In the main text we give the undoubtedly improved version of FE (→GE,EE).

We add cautionary  before d1 and f1. The sign before f1 was already added in GE2 – and subsequent ones – and in EE4.

Lack of the  mark in EE2 is a part of a bigger mistake – in this edition all dynamic hairpins in bars 71-78 were omitted.

No fingering in CLI & FE (→GE)

Chopin's fingering in FES

Fingering in EE

..

We openly give the fingering added by Chopin in FES in bar 77 in the main text, as its universal character does not raise any doubts. Identical fingering was added by Fontana in EE, additionally complemented in bar 78.
