b. 217

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

d1 in GC (→GE), FE3 (→FE4) & EE

No d1 in FE1 (→FE2)

..

No d1 notes in the 3rd and 4th chords in the R.H. is certainly a mistake of the engraver of FE1 (→FE2), corrected by Chopin in FE3 (→FE4) and the base text to EE.

b. 218

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

..

The notation of accidentals in the penultimate chord in the R.H. in bar 218 is inaccurate in the sources. The  raising e2 to e2 is absent in all sources, whereas the  raising g2 to g2 is present only in GE and EE.

b. 218-219

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

GC includes identical sets of accidentals in the last chord in the R.H. in bar 218 and the first one in bar 219 – a  before the top bottom note (d2) and a  raising g2 to g2. In GE1, the  in bar 218 was printed before e2, which has to be considered to be a mistake, as the sign before dwas placed correctly, whereas the  before eshould have been already in the previous chord. In GE2 it was noticed that in bar 219 the  is supposed to concern the adjacent note, e2, however, the erroneous notation of bar 218 was left unchanged. FE (→EE) include the correct notation.

It is worth observing that in GC and FE the  before gin the last chord in bar 218 is not unnecessary, as the sign is absent in the previous crotchet.

In the main text, we add a cautionary  before din bar 218.

gis1 in chord in GC (→GE)

No g1 in FE (→EE)

No bottom g1 is certainly an oversight of the engraver of FE (→EE).

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

..

The  raising c2 to c2 at the end of bar appears only in FESch (written in), FE4 and EE2. The absence of this accidental constitutes an undoubted oversight by Chopin in [A] – cf. e2 and not e2 in an analogous passage in bars 91-92.
