b. 216

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

..

In the main text we add a cautionary at e(Chopin wrote the corresponding accidental in bar 215).

b. 216

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

a-c1-e1 in GC & FE (→EE)

a-e1 in GE

..

The absence of c1 in GE in the last crotchet is most probably the oversight by the engraver, influenced by similar figures in the preceding bars.

b. 217

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

..

In GC (→GE1) the bar includes only 5 crotchets, as the copyist overlooked the third chord. The mistake was corrected in GE2.

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. 217-218

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

in GC (→GE)

No indication in FE (→EE)

..

The absence of cresc. in FE (→EE) is most probably a result of the engraver's inaccuracy.
