Chord with c2 in GC & FE1 (→FE2EE1)

Chord with c2 in GE, FE3 (→FE4) & EE2

..

The chord with c2, although completely possible from the harmonic point of view, is, however, most probably a result of Chopin's mistake, as the d-f-a-c (a-c-e-g) diminished four-note-chord introduces the B minor key, which Chopin indicated with an enharmonic change in the previous bar. In this context, an omission of a  is highly likely – cf. the note in bar 56. The natural added – probably by Chopin – in FE3 (→FE4) is, therefore, probably a correction of a mistake.

b. 95

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

..

In GC (→GE) and FE1 (→FE2EE) there is no accidental before the top most note of the last chord. This patent inaccuracy of Chopin notation was corrected in FE3 (→FE4), at the same time, however, the  raising a1 to awas overlooked.

b. 110-114

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

..

In GC and FE1 (→FE2EE1), there are no accidentals before the 3rd crotchet in bars 110 and 114. It is certainly an oversight of Chopin in [A], corrected in FE3 (→FE4). The naturals were added also in GE (in GE1 only in the top voice) and EE2.

b. 112

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

..

There are no accidentals before the chord on the L.H. on the 2nd beat of the bar in GC and FE (→EE1). The necessary  raising c1 to c1 was added in GE and EE2. In the main text we add a cautionary  before e1.

b. 145-155

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

..

In the sources based directly on [A] there are no naturals raising c to – in GC in bars 145 and 147, in FE1 in bar 147. These patent inaccuracies were corrected in GE and FE2, so that all the remaining sources include the correct text. Similarly in bars 153 and 155, although there and in FE the second  was added only in FE4.
