b. 17-19

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

No fingering in AI & A

Fingering in FE (→GE)

..

We give the fingering added by Chopin in a proofreading of FE (→GE). In EE3 the digits in bar 17 were omitted, which was only partially and erroneously corrected in EE4.

b. 17

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

Quavers in AI

Dotted rhythm in A (→FEGE,EE)

..

The rhythm of AI is undoubtedly the original version of this motif, most probably changed at the time of writing A. It is indicated by gaps between the notes of this motif, corresponding to equal quavers.

b. 17-20

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

No slur in AI

Slur in A (→FEGE,EE)

..

The slur of A (→FEGE,EE), beginning in the 2nd bar of a new phrase, was completed by Chopin in FED. We consider this addition as an improvement of notation and adopt it to the main text.

b. 17-26

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

No pedalling in AI & A

Pedalling in FE (→GE,EE)

..

Chopin added the entire pedalling in this section of the Etude while proofreading FE (→GE,EE). See also bars 22-23, 29-32 and 33-36.

b. 17-18

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

No markings in AI

 i cresc. in A (→FEGE,EE)

..

Lack of dynamic indications in AI is probably a result of its working nature. However, it cannot be excluded that the idea of the phrase's dynamics, which Chopin had while writing AI, did not coincide with the final concept written later in A (→FEGE,EE). Cf. the note on accents in bar 18.
