b. 72

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

 in A & GE2

No sign in GE1 (→FEEE)

..

The missing  sign in GE1 (→FEEE) is certainly an oversight of the engraver of GE1. The mistake was corrected in GE2 after A.

b. 72-74

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

..

In A there is no octave sign over the entire sequence of chords written with small notes. The patent mistake was corrected already in GE1 (→GE2,FEEE), which could have been a result of Chopin's proofreading (however, the correction could have also been implemented by the reviser, since due to the overlapping of the hands, the mistake is evident).

b. 72

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

3 accents in A

No marks in GE1 (→FEEE)

1 accent in GE2

2 accents &  suggested by the editors

..

Interpretation of three accents written in A at the beginning of the bar is problematic, which could have been the reason they were omitted in GE1 (→FEEE). In the main text we suggest a solution in which the first two signs are reproduced without changes and the third is interpreted as diminuendo, which, undoubtedly, is required here between the accent at the beginning of the bar, which ends the two-bar crescendo, and the  after the last trill. In GE2 only one accent was reproduced, corresponding to the first two in the notation of A.

Slur over R.H. in A

No slur in GE1 (→FEEE)

Slurs in both hands in GE2

..

The missing slur in GE1 (→FEEE) is certainly an oversight, completed in GE2 after A. The same slur was added in GE2 also in the L.H.

Fingering written into FED

The Chopin fingering is probably written with a pupil's hand.
