In FE1 the  sign was placed after the 2nd crotchet, which may be a result of a misinterpretation of Chopin's notation by the engraver – cf. three preceding bars.

b. 280

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

Slur to d1 in A

Slur to e1 in GE (→FEEE)

The slur of A seems to be inaccurate – in this context it is difficult to assume that ewere to be separated from the previous quavers (cf. analogous bar 132). Therefore, the version of GE may be a result of Chopin's proofreading.

b. 280

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

E in A & GE2

E-e in GE1 (→FEEE)

..

The version of GE1 (→FEEE) may be a result of Chopin's proofreading, although the lack of any traces of performing changes in this place in GE1 suggests that it could be a mistake of the engraver. Doubled E on the 4th crotchet seems to be superfluous – e is present in the cello part, whereas introducing octaves only from the 1st chord in bar 281 subtly underlines the entrance of an enhanced repetition of the first phrase of the theme. In the corresponding bar in the exposition (bar 132), e is not present in the solo part in any of the sources.

Slurs in A & GE2

Slur in FE (→EE)

In the main text we give the slurs of A (and GE2), certainly the only authentic ones – cf. the corresponding place in the exposition, with identical slurs in all sources. The slurs of GE1 are inaccurate here, whereas in FE (→EE) the first of them was omitted on top of that.
