b. 278-279

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

No slurs in A

3 slurs in GE (→FEEE)

..

The slurs of GE (→FEEE) could have been added by Chopin; however, according to us, it is highly unlikely due to their schematic range, whose relationship with the figuration's structure is largely unconvincing.

b. 278

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

4 crotchets in A (→GE)

3 crotchets in FE (→EE)

..

According to us, omission of the additional quaver stem next to f1 is a result of the Chopin proofreading of FE (→EE), which is indicated by possible traces of correction in print in this place (e.g. a slightly bigger note head of the note). Taking into account the fact that in analogous bar 130 f1 is not extended, one can come to a conclusion that Chopin could have written the fourth stem in the discussed bar by mistake.

b. 278-280

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

4 accents in A & GE2

3 accents in GE1

4 accents in FE

4 accents in EE

..

The omission of the last accent in bar 280 in GE1 must be a mistake. The accent was added in FE, yet it was placed inaccurately, as a result of which it is uncertain whether it applies to the 2nd or the 1st quaver of the triplet (the 1st accent in bar 278 in FE is even more inaccurate; we interpret it to apply to the 1st quaver in the bar). In EE, three out of four accents were put a quaver earlier, on the 1st or 7th note in the bar, which is a mistake.

Fingering written into FEH

No teaching fingering

..

The digits in FEH are not written by Chopin's hand, hence it is uncertain whether they come from a lesson with Chopin.

..

In both bars, FE (→EE,GE1GE2) feature a cautionary (?)  before d3. The superfluous marks were removed only in GE3.
