b. 21

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

All sources repeated a on the e2 sound, which implies that it was written by Chopin in [A]. It is a superfluous cautionary sign so we omit it in the main text.

b. 22

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

GC and FE1 (→FE2→FE3) do not include naturals before the octave on the 4th quaver of the bar. The flats before g2 and g1 in the 2nd half of the bar prove Chopin's oversight. The naturals were added in GE and EE, as well as in FE4.

 and cresc. were probably added by Chopin in [A] after GC had been prepared (unless the copyist forgot to write them in GC). Actually, both indications are present already in FE1, which certainly was not corrected by Chopin. Anyways, it is impossible that Chopin resigned from them, as they would have had to be deleted in GC.

FE1 includes an erroneous  before the top note of the last third. All the remaining sources feature the correct .

No accidental in GC (→GE), FE1 (→FE2) & EE

 raising d2 to d2 in FE3 (→FE4)
..

The natural raising d2 to d2, added – most probably by Chopin – in the proofreading of FE3 (→FE4) is most likely a correction of a mistake and not a new version of this detail. The bottom notes of the dyads (and in the chords also the middle ones), unless they are an octave doubling of the top voice, always belong to the components of a current chord in the entire section comprising bars 17-36.
