b. 2-4

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

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).

Fingering in A

Wedge in FE (→EE)

Wedges in GE

Our variant suggestion

..

The wedges over and are a result of a mistake of the engraver of FE, who misinterpreted the '1's of the fingering. The first of them was removed in the last proofreading of FE (→EE), yet in GE it remained unchanged. In the main text we give the fingering after A, yet we leave the inclusion of the digit over to the performer's discretion, as in subsequent, similar figures (bars 4, 6, 8), Chopin did not once repeat it and it cannot be excluded that it referred to the original version of this fragment.

Fingering in A

FE (→GE,EE)

..

In the main text we give the fingering of the L.H. written by Chopin in A. Only some of these digits were correctly reproduced in FE (→GE,EE). The editors assume that the most probable reason for this state of affairs is rather the engraver's negligence than Chopin's proofreading.
