Issues : Omission of current key accidentals

b. 56

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

..

Before the octaves on the 2nd and 3rd crotchet of the bar in FE1 (→FE2FE3) there are no accidentals. The patent inaccuracy of the composer was corrected to a varied extent in EE1 (the naturals of and C) and FE4 (the naturals of and C1-C). The totally correct notation is included in GE and EE2. Same in bar 244.

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.
