Issues : Errors of A

b. 40

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

..

In the sources the  returning dis missing both before the last demisemiquaver and the next two notes at that pitch. Chopin's oversight is undeniable, yet if we were to evaluate the sound only, one can ponder whether the  was supposed to be already before the last demisemiquaver or only before the dotted quaver in the middle of the bar. From the psychological point of view, the second possibility is much more likely: it is hard to assume that Chopin would have forgotten an accidental differentiating two adjacent notes in a chromatic passage.

On the 3rd beat of the bar A does not have flats lowering c1(2) to c1(2), which is Chopin's patent oversight: the A minor key is valid already from bar 37 and in the discussed bar it was confirmed by a  before the top most note of the passage in the 1st half of the bar. The sign in the R.H. was added already in GE (→FEEE), whereas the  in the L.H. was added only in GE2

In A (→GEFE) there is no treble clef in bar 50 (we do not include the sign written in pencil with a foreign hand, probably later). In GE (→FE) the bass clef in bar 49 was also overlooked. The mistake was corrected in EE.

In A there are no naturals raising g1(2) to g1(2). It is undoubtedly an oversight, corrected already in GE (→FEEE).

b. 72-74

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

..

In A there is no octave sign over the entire sequence of chords written with small notes. The patent mistake was corrected already in GE1 (→GE2,FEEE), which could have been a result of Chopin's proofreading (however, the correction could have also been implemented by the reviser, since due to the overlapping of the hands, the mistake is evident).
