b. 276

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

..

Same as in analogous bar 128, in A there is no accidental before the crotchet in the middle voice. It must be an oversight, corrected already in GE1 (→FEEE, →GE2).

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. 280

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

E in A & GE2

E-e in GE1 (→FEEE)

..

The version of GE1 (→FEEE) may be a result of Chopin's proofreading, although the lack of any traces of performing changes in this place in GE1 suggests that it could be a mistake of the engraver. Doubled E on the 4th crotchet seems to be superfluous – e is present in the cello part, whereas introducing octaves only from the 1st chord in bar 281 subtly underlines the entrance of an enhanced repetition of the first phrase of the theme. In the corresponding bar in the exposition (bar 132), e is not present in the solo part in any of the sources.
