Slurs

b. 1-2

composition: Op. 10 No 10, Etude in A♭ major

9 slurs in A (→FE)

11 slurs in GE & EE

No slurs—our alternative suggestion

..

It is unclear how to treat the short, two-quaver-long slurs visible in the sources. They do not raise any doubts in A, in which they are compatible with the accents over each sixth. However, after removal of the majority of accents in a proofreading of FE (→GE,EE), the slurs seem not to correspond to the new accentuation. The fact of leaving them could have been a compromise, whose aim was to avoid an additional, significant complication of a proofreading. On the other hand, it cannot be excluded that Chopin removed the accents in order not to change their layout, but to avoid exaggeration resulting from double indications. Therefore, having no absolute certainty of Chopin's intention, we suggest a version without slurs as a recommended alternative to the main text from A (→FE).
In GE and EE the authentic slurs were complemented with another two in the 2nd half of bar 2, which does not have any influence on the performance, as in each case the slurs are to be considered as a model and binding in bars 1-4 (in A) or 1-8 (editions).

Slur ending in A

FE (→GE,EE)

..

The slur of FE (→GE,EE) is obviously erroneous – the engraver led the slur to the end of the line, as it is in A. At the same time, he did not pay attention to the difference in the text's division into great staves: in A the line ends with bar 8, while in FE – with bar 9.

No slurs in A (→FEGE,EE3)

Slurs in EE4

..

The slurs in the L.H. added in EE4 are certainly non-authentic.

Slurs in A, contextual interpretation

No slurs in FE (→GE,EE)

..

According to us, both slurs written in A are too short. Their absence in the editions is probably a result of an oversight of the engraver of FE (it cannot be excluded that he omitted them, not being certain of their range).
