b. 1

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

No indications in CLI

in FE (→GE,EE

..

In CLI there are no performance indications in the entire Etude. Both the indication of tempo and articulation was most probably added by Chopin in proofreadings of FE (→GE,EE) – cf. the beginning of the Etude in A minor, No. 2.

b. 1

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

No indication in CLI

 in FE (→GE1GE2­→GE3­→GE4, →EE

Our suggestion (GE5)

..

The  indication in FE (→GE1GE2GE3GE4, →EE) seems to concern only the semiquavers in the R.H. According to us, as it is hard to suppose that the long resounding octaves in the L.H. were to be played in different dynamics, it should be assumed as an inaccuracy of the notation. A respective change was also introduced in GE5. See also bar 45.

b. 1-11

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

No fingering in CLI

Fingering in FE (→GE

Additional fingering in EE

..

The fingering in bars 1, 4 and 11, as the entire fingering given in the main text of the Etude based on FE (→GE,EE), certainly comes from Chopin. In EE Fontana completed it in bars 2 and 8-10 with the digits describing the fingering indicated by Chopin in a slightly more accurate manner.

b. 1-2

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

No accents in CLI & EE2

Accents in FE (→GE) & EE3 (→EE4

..

In both known copies of EE2, the omitted accents were added by hand. They were also added in the later impressions of EE.

b. 1-11

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

No pedalling in CLI

Pedalling in FE (→GE1GE2, →EE

Pedalling in GE3 (→GE4GE5

..

In the main text we give the undoubtedly authentic pedalling of FE (→GE1GE2,→EE). In later GE the indications were omitted – presumably by mistake – in bars 9-10.
