b. 4

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

..

FE (except for FE4) lacks in five necessary accidentals – naturals before d2 and b and sharps before ff2 and g2. This patent inaccuracy certainly has its source in the notation of [A]. Similarly in GC, in which, however, Chopin added a  raising b to b. In GC (→GE) there are also no naturals before the last octave in the R.H. – it can be an oversight of the copyist or a later addition in [A]. In the remaining sources the signs were completed (all additions can be attributed to a revision): three were added in EE1 and FE4, four in GE; only EE2 includes the correct notation. Cf. bar 24.

b. 8

a in chord in GC (→GE) & FE2 (→EE,FE3FE4

a in chord in FE1

The version with a in FE1 is certainly not intended by Chopin, which is proved by the  before the note in the respective bar of the recapitulation, which was not written in the base text to FE, as well as the compatible text of the remaining sources in the discussed bar. The engraver, instead of a , wrote an erroneous  before this note (unjustified in this context).

b. 24

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

..

In GC and FE (except for FE4) five necessary accidentals are missing – the naturals before d1d2 and b and sharps before f2 and g2. This patent inaccuracy certainly stems from the notation of [A]. Three of them were added in EE1, four in FE4; only GE and EE2 include the correct notation.

b. 25

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

..

The naturals before the 3rd octave of the bar are only in EE, FE4 and GE2. Chopin's patent inaccuracy was completed by revisers in probably all cases (certainly in GE2).

b. 29-30

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

..

The notation of accidentals in this passage is inaccurate in the sources, which, however, does not impede the interpretation of the correct text. In GC and previous FE, eight sharps are missing – before fcf1 and c2 in the L.H. and before c2f2c3 and f3 in the R.H. In EE, GE and FE4 the signs were added, but only GE2 includes the fully correct notation.
