b. 344

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

f1 in A (→GE)

a-f1 in FE (→EE), contextual interpretation

..

The addition of a in the proofreading of FE (→EE) is undoubtedly a Chopin improvement (it can be that Chopin corrected his own oversight in A). There is no extending dot next to this note, which, regardless of the reason, has to be considered an inaccuracy in this context.

b. 346-347

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

..

In FE the bottom notes of the last chord in bar 346 and the first one in bar 347 are switched – g1 is in bar 347 and a1 in bar 346. This patent double mistake was corrected in EE.

b. 346

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

..

In GE1 the semiquaver opening the characteristic main motif of this movement of the Concerto, recalled here, is A-f. This patent mistake, corrected both in FE (→EE) and in GE2, is probably a result of an unfinished proofreading of A, erroneously printed in this place – the correct note was added, yet the erroneous one was not removed.

b. 348

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

f1 in A (→GE)

f-f1 in FE (→EE)

..

The note added in the proofreading of FE (→EE) is a change that certainly comes from Chopin. He also introduced a similar complement in the Concerto's 3rd mvt, bars 63-64.
