b. 297

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

Shorter  in A & EE

No sign in GE1 (→FE)

Longer  in GE2

..

The absence of the  hairpin in GE1 (→FE) may be an oversight of the engraver or Chopin's proofreading – see bars 293-295. The sign in EE may be a part of a revision unifying the markings after analogous bars 293 and 295. The sign in GE2 was added taking into consideration A, yet the range of the  was repeated after GE1 in bar 293.

b. 303-304

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

Whole-bar slur in A

Motivic slur in GE1 (→FE)

Motivic slurs in both hands in EE & GE2

..

The slur of A is probably the original version – cf. bars 301-302. Therefore, the longer slur in GE (→FEEE) may be a result of Chopin's proofreading.
The slurs in the L.H. added in EE and GE2 are inauthentic – see bars 297-298.

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

..

In A there is not any  raising e2(3,4) to e2(3,4). It is almost certainly Chopin's mistake – if he were to hear e in this place, he would have used a cautionary flat in this context. The composer also omitted the naturals raising d1(2) to d1(2), which clearly proves that the figures (whose sound, written after so many repetitions, he regarded as obvious) were written hastily and inaccurately. Anyway, the naturals (e2d2 and e4) added in the proofreading of GE1 (→FEEE, →GE2) and uncontested by the composer both in FE and FED clearly prove his intention. In EE, naturals were added also next to d1 and d4, whereas in GE2 – next to e3.

b. 310

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

..

The natural raising a to is written in A with pencil. The sign clearly differs from both typical Chopinesque naturals and the signs added in bar 314 (as well as from the  written with pencil in the part of the clarinet I in Morch in this place). Moreover, a denser text in GE1 suggests that in this edition a corresponding sign was added only in the proofreading. Therefore, it may be one of the later, foreign additions – cf. bar 256.

b. 335-336

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

No slurs in A

Slur in bar 336 in GE1 (→FE)

Double slurs in EE

Slur in bar 335 in GE2

Slurs suggested by the editors

..

In the main text we add the slurs in the L.H. on the basis of the respective bars in the exposition. The slur in bar 336 was added already in GE1 (→FE), perhaps by Chopin. EE introduced double slurs, same as in the previous, analogous bars in the recapitulation. GE2 added a slur in bar 335 and removed the one in bar 336.
