AI is missing pedalling markings.

b. 1

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

Agitato in AI

. = 92 in A

. = 96 in FE (→GE,EE)

..

The way of writing the indication of tempo-character in A suggests that Chopin was gradually developing this indication. Initially, it included only Agitato (as in AI), to which then Molto and eventually Allwere added. The change of the value in the indication of the metronome tempo is most probably a result of Chopin's proofreading of FE (→GE,EE).

Slur in AI

FE (→GE1), possible interpretation

GE2 (→GE3GE4) & EE

..

Neither in A nor in FE are the slurs in these bars precise. The slur of A gradually fades due to the ending ink, hence it is uncertain where it was supposed to end, according to Chopin. In FE (→GE1) the doubt concerns the transition to the new line between bars 2 and 3 – the slur in bar 2 suggests continuation (in accordance with A), which is, however, not confirmed by the new slur in bar 3. Although the slur in AI is legible, in this manuscript, the slurs generally seem to be written very randomly, without the intention of creating a coherent, complete image of phrasing or articulation (convergence with the 2nd slur of FE is most probably coincidental). According to us, there is no reason to think that the slurring here could differ from analogous indications in bars 10-12, embraced with one slur both in A and in the editions. Cf. bar 47.

Mordents in AI & A

No ornaments in FE (→GE,EE)

..

From the very beginning, the mordents constituted an integral part of the main theme of the Etude. Eventually, however, while proofreading FE (→GE,EE), Chopin resigned from them in the first section of the piece (cf. bars 38-39).
