b. 34

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

Long accent in AI

Short accent in A (→FEGE,EE)

..

The accent in A may be regarded as short, and that is how it was reproduced in the editions. However, the mark is shifted to the right of the note which suggest the intended use of a long accent. A clear long accent is written in AI.

b. 36

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

No  sign in AI & A (→FEGE1)

 in EE & GE2 (→GE3GE4)

..

In the pedalling of bars 29-36, added in a proofreading of FE, the last  mark in bar 36 was omitted, which is almost certainly a mistake. The error was repeated only in GE1.

b. 37-48

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

..

In AI there is the indication come sopra, written several times on the lower stave, which in this context undoubtedly refers to bars 1-12 and means repetition of the notation of the part of the L.H. of these bars in bars 37-48.

b. 37-48

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

No fingering in AI & A

Fingering in FE (→GE)

..

In bars 37, 45 and 48 Chopin added '4' digits in a proofreading of FE (→GE), resembling the basic fingering scheme of the Etude. In EE Chopin's hints were completed in bars 37-45, adding 18 fours under notes.
