b. 129-131

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

..

Same as in bars 121-123, in GC in the part of the left hand only the top notes of the octaves are written (except for the last two in bar 131). The bottom ones were marked in an abbreviated manner with the help of the con 8va - - - indication.

We add cautionary flats before b-b1. The signs were added already in GE and EE2.

b. 129

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

..

GC has no  before the 2nd quaver, which is most probably an oversight of the copyist. The mistake was corrected in GE. The remaining sources include the correct text.

b. 131

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

Minim & semibreve in GC (→GE)

No inner notes in FE1

Minims in FE2 (→EE,FE3FE4)

..

In the main text we give the undoubtedly correct rhythmic notation of the middle notes of the chord, transmitted by GC (→GE). Among the remaining versions, the first is erroneous, whereas the second – inaccurate (probably due to a misunderstanding of the notation of [A]).
