b. 278

composition: Op. 39, Scherzo in C♯ minor

..

In GC, this bar is marked as the repetition of the previous one, which must reflect the notation of the autograph.

b. 278

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

Long R.H. accent in A (literal reading→GEFE)

R.H. short accent in EE

L.H. long accent in A, interpretation suggested by the editors

..

Same as in bar 130, we consider that it is more likely that the accent refers to the L.H.

b. 278

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

..

In A there is no  restoring a. This patent mistake – cf. analogous bar 130 – remained unnoticed by Chopin both during the proofreading and lessons. Revisers of the editions also did not notice it.

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.
