Slurs

b. 1

composition: Op. 25 No 1, Etude in A♭ major

..

In both autographs the moment of starting the slur is not entirely clear. In the case of AI we can rely only on a photography, hence, there is no certainty whether all details of the original are clearly visible on it (it is possible that, e.g., the initial fragment of the slur was written with such a delicate line that it is invisible on the photography). According to us, in both cases there is no doubt that, as far as the shape of the slur is concerned, Chopin wanted to begin the slur in the most natural way possible in this context, i.e. from the beginning of the phrase, hence from the beginning of bar 1 in AI and from the upbeat in A (this is how it was interpreted in GE). Such an interpretation of A is confirmed by the slurs of FE and EE, based on other manuscripts.

b. 7-8

composition: Op. 25 No 1, Etude in A♭ major

Two slurs in AI & A

One slur in GE, FE & EE

..

It is unclear on which ground GE embraces these bars with one slur. According to us, it is a result of misunderstanding A. One slur is, however, also present in FE and EE, hence this version may be considered as an equally valid alternative to two slurs written in AI and A.

b. 11-12

composition: Op. 25 No 1, Etude in A♭ major

Two-bar long slur in AI, A (→GE) & FE

Two slurs in EE

..

The broken slur of EE may result from misunderstanding of the manuscript, perhaps inaccurate. In A, bar 11 closes the line; this layout, conducive to ambiguities in the slurs' notation, was probably repeated in the manuscripts which served as base texts for FE and EE.

b. 14-15

composition: Op. 25 No 1, Etude in A♭ major

Broken slur in AI, FE, EE2 (→EE3) & GE2 (→GE3)

Continuous slur in A (→GE1GE1a) & EE1

..

The compatibility of the slurring of AI and FE (here and in bars 15-16) is puzzling, as a coincidence seems to be highly unlikely. Chopin could have returned to the original slurring in the base text to FE or at the time of proofreading this edition, so the issue whether the long slur written in A is the expression of Chopin's final intention cannot be conclusively resolved.

b. 15-16

composition: Op. 25 No 1, Etude in A♭ major

Broken slur in AI & FE

Continuous slur in A (→GE) & EE

..

The slurring of AI and FE points to one-bar motifs in the internal voices.
