b. 415-417

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

..

In A, bars 415 (from the 2nd beat), 416 and the 1st quaver in bar 417 are written an octave lower, since they were not encompassed with the octave sign. This patent mistake was corrected – perhaps by Chopin – already in GE1 (→FEEE, →GE2).

b. 415-423

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

..

A (→GE) features a das the penultimate quaver in bar 415. In the proofreading of FE (→EE), Chopin changed the notation of this note to e2. He performed an identical change in the notation of the topmost note of the chord on the penultimate quaver in bar 423. Similarly in bars 455 and 463.

Slur in A & GE2

2 slurs in GE1

Slur in bar 416 in FE (→EE)

..

The division of the slur in GE1 is a distortion of slurring, characteristic of this edition. In any case, the absence of the slur in bar 415 in FE (→EE) suggests that the slur in bar 415 was added in GE1 only in the last phase of proofreading, as a simplified correction of a too short slur, encompassing only bar 416.

b. 415-416

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

No slur in sources

Slur suggested by the editors

..

According to us, the absence of the slur in the L.H. is a result of Chopin's oversight: a respective slur is present in all three similar places, in bars 423-424, 455-456 and 463-464.

3 long accents in A & FE

 & > in GE1

3 short accents in EE & GE2

..

Three clearly long accents written in A were reproduced in GE1, without any apparent reason, in an explicitly varied manner. However, FE restored the notation of A, which could be seen as Chopin's proofreading. Both in EE and GE2 the Chopinesque long accents were reproduced as common short accents.
