b. 1

composition: Op. 10 No 7, Etude in C major

88 in A

84 in FE (→GE,EE)

..

Chopin changed the prescribed tempo of the Etude twice: in A he deleted Presto and wrote Vivace, while in a proofreading of FE (→GE,EE), he slightly reduced the metronome tempo. Cf. changes of a similar nature in the Etudes in E major, No. 3 and C minor, No. 12.

In the main text we give the title and dedication in the undoubtedly authentic version adopted in FE. The extensions of both the title (in GE and EE) and dedication (in EE) most probably come from the editors. See Etude in C, No. 1, bar 1.

Fingering in A

FE (→GE)

..

In the main text we give the fingering in the R.H. written by Chopin in A and then completed in a proofreading of FE (→GE). In EE the fingering was carefully completed by Fontana, also in the L.H.

Slur from g in A (→FEGE,EE)

Our suggestion

..

According to us, separating the accented a note from the following quavers is unnatural in terms of both articulation and phrasing. It is confirmed by the slurring of similar bars 2, 5-6, 34-35 and 38-39 – a and g are combined with a slur in five out of seven places in A and in all seven in FE. Therefore, in the main text we suggest a slur beginning already from the 3rd quaver in the bar.
