b. 325-326

composition: (Op. 4), Sonata in C minor, Mvt IV

in A

Longer  in GE (→FE,IE)

No sign in EE

..

In the main text we reproduce the  hairpin entered into A. In GE (→FE,IE) the mark was arbitrarily extended, as a result of which it spans almost two entire bars (a similar situation is to be found 4 bars later). The absence of the mark in EE is most probably due to the engraver's oversight.

composition: Op. 21, Concerto in F minor, Mvt III

No slurs in A (→GE1FE)

Double slurs in EE

Slur in bar 327 in GE2

Slurs suggested by the editors

..

In the main text we add slurs in the L.H. in bars 326-328 and 334 after the respective bars in the exposition. A simplified notation – slurs only in bars 325 and 333, most probably as a model for the next bars – is probably a result of Chopin's increasing haste at the time of writing A. In EE double slurs were added in these bars, same as in bars 325 and 333. In GE2 a slur was added only in bar 327 (and 335).

b. 326

composition: Op. 21, Concerto in F minor, Mvt III

Slur over quavers in A & GE2

Slur from crotchet in GE1 (→FEEE)

..

Adjusting slurs to bars is a characteristic manner of the engraver of GE1. The version of A was restored in GE2.

Slur in A, literal reading

Slur in A (contextual interpretation→GEFEEE)

..

When interpreted literally, the slur of A does not exceed bar 326. However, its shape suggests leading it to the beginning of bar 327, which is confirmed by the corrected – most probably by Chopin – slur of GE (→FEEE).
