Literal reading of slur in A (→FE)

Possible interpretation of A & slur in GE & EE

Interpretation of A suggested by the editors

..

The slur of A in bar 39 unanimously suggests a continuation, which is, however, not confirmed in bar 40, on a new page, where the slur is missing. In FE the slur was correctly reproduced in terms of graphics, yet it is hard to assume that Chopin had such a slur in mind. Both in GE and EE the slur was extended in such a way to dissipate the doubts concerning its scope. We suggest a different interpretation.

Slur in A, interpretation

No slur in FE (→GE,EE2)

Slur in EE3 (→EE4)

..

The vague mark in A may be interpreted as a slur. It seems that Chopin went out of ink at the time of writing, however, he did not take care of a discernible notation in A, nor did he add the slur while proofreading FE. Therefore, we do not include this mark in the main text. In EE3 (→EE4) a whole-bar long slur was added under the semiquavers.

Extension of the marks in the editions stem from the engravers' inaccuracy and manners.
