b. 68

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

F & f in A (→GE)

F1 & F in FE (→EE)

..

Moving the 2nd crotchet an octave lower is undoubtedly a result of a Chopin proofreading of FE (→EE). He introduced an identical change in an analogous situation in bar 76.

FE has an erroneous finstead of epresent in A (→GE) as the 3rd note of the passage in the L.H. The patent mistake was rectified in EE.

E in A (→GE)

G in FE (→EE)

In the main text we give G introduced by Chopin in the proofreading of FE (→EE). FE1 overlooked a  before this note, which was then added in FE2.

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

E & e in A & GE2 (staccato)

E & e in GE1 (no dot)

E1 & E (no dot) in FE (→EE)

E1 & E (staccato) suggested by the editors

..

Same as in the previous phrase, Chopin moved the 2nd crotchet in the part of both hands an octave lower while proofreading FE (→EE). The given variants include the presence or absence of the staccato dot overlooked in GE1 (→FEEE), together with three previous ones.

b. 77

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

Chord with e1 in A (→GE)

Chord without e1 in FE (→EE)

Our variant suggestion

..

The version of FE (without e1) could be considered a result of Chopin's proofreading if it were not for a mistake in this chord present in FE1 – it is a g (with a ) instead of that is the bottom note there. The mistake is obvious and it was corrected in FE2 (→EE); however, it means that Chopin did not notice such serious mistake in the chord he was just proofreading when he was possibly removing e1. It seems to be impossible, hence the absence of this note must be considered an oversight. Therefore, we include it in the main text, but only in brackets, since the composer could have accepted a version without ewhile proofreading FE2 in this place.
