b. 242

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

No sharps in GC (→GE) & FE1 (→FE2EE1)

Sharps in FE3 (→FE4) & EE2

..

Same as in bar 54, we include in the main text the sharps raising the f1-f2 grace note to f1-f2, added – most probably by Chopin – in the proofreading of FE3 (→FE4). The change was introduced also in EE2.

b. 245

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

Chord with c2 in GC & FE1 (→FE2EE1)

Chord with c2 in GE, FE3 (→FE4) & EE2

..

The chord with c2 is most probably a result of an oversight of the composer, which is confirmed by the  added – probably by Chopin – in FE3 (→FE4).

b. 264

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

Octave in GC (→GE)

Chord in FE (→EE)

..

The comparison with analogous motifs in a few places of Scherzo proves that the missing g2 note on the last crotchet is almost certainly a mistake of the copyist.

b. 275

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

..

EE1 has erroneously g instead of a as the inner note of the last L.H. chord. The mistake was corrected in EE2.
