b. 81

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

d-a-d1 in GC (→GE) & FE2 (→EE,FE3FE4)

a-din FE1

..

No d in the 1st crotchet in the L.H. is undoubtedly an oversight of the engraver of FE1.

b. 85-88

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

..

In the main text we add a cautionary  next to the top note (g) of the last chord in each of these bars. These accidentals appear in the sources only in bar 86 (in GE and EE2) and in bar 87 (in all sources).

b. 89

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

..

When interpreted literally, the last chord's 2nd note from top in GE1 is a d2, which is a patent mistake with respect to the d1 note played simultaneously in the L.H. The regular structure of the three-chord motifs points to a Terzverschreibung, and not to an oversight of a . This is how it was corrected in GE2, i.e. to b1.

b. 90

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

..

The notation of accidentals is inaccurate in the majority of the sources, which, however, does not cause any difficulties in the interpretation of the text. In the 2nd half of the bar, GC and FE have only one sign: a  before the last chord in the R.H., whereas in FE it restores f2, while in GC – probably erroneously – it raises g2 to g2. GE added to the  written in GC another one, raising b2 to b2. Only EE includes all necessary signs. Moreover, all sources include a superfluous  before d1 in the 3rd crotchet in the L.H. In the main text, we omit this sign, in turn, we add a cautionary  before f3 (in the last chord).
