b. 257-258

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

4 slurs in A, contextual interpretation

3 slurs in GE (→FEEE)

2 slurs suggested by the editors

..

In A, Chopin embraced this pair of bars with one slur, which he then clearly divided into two, in accordance with the slurring of similar pairs of bars in the three remaining fragments of this movement of the Concerto, built upon similar phrases (bars 177-182, 353-364 and 494-499). The fact that the division was not included in GE (→FEEE) can be most probably explained by an arbitrary decision of the engraver of GE1.
In accordance with the General Editorial Principlesp. 16, in the main text we omit "triplet" slurs.

Appoggiatura in FE (→EE)

Acciaccatura in GE

Like in bar 255, in the main text we give a long grace note on the basis of FE (→EE). The slashed grace note in GE is either an inaccuracy or routine revision.
