b. 92

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

f2-d3 in GC (→GE) & FE3 (→FE4)

f2-f3 in FE1 (→FE2EE)

..

The version of FE1 (→FE2EE) is certainly erroneous – it is proved both by the text of GC (→GE) and the proofreading of FE3 (→FE4). At the same time, it is only FE4 that includes a completely correct text, as FE3 overlooked the  before the corrected note.

b. 92

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

..

In all sources, there is a cautionary  before f2. In the main text we omit this sign, which is unnecessary in this context.

b. 93

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

..

At the beginning of the bar GC has a C1-E tenth. It is certainly a mistake, which is proved by, among others, the  before the bottom note, which does not make any sense before C1. All the remaining sources include an E1-E octave.

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

No slur in GC (→GE)

Slur in FE (→EE)

..

There are no reasons to doubt the authenticity of the slur of FE (→EE), although it is not certain whether it was overlooked in GC or added in [A] already after the copy had been prepared.

Slur in GC, probable interpretation

Slur in FE (→EE)

No slur in GE

Probable slur in [A]

..

The suggested reconstruction is based on a joint consideration of the slurs in the L.H. in GC and FE. Both the copyist and the engraver of FE had in front of them the same Chopin's autograph and it is highly likely that each of them reproduced one part of the slur, which in [A] was divided due to the end of the page (line). It can be assumed that the engraver of FE1 overlooked only a short fragment of the slur in bar 93, whereas the copyist – the slurs in the next three bars. This kind of reasoning is also justified by the adopted interpretation of the unfinished slur of GC (overlooked in GE). According to us, the slur of FE can be considered to be equal, as Chopin could have accepted it in relation to the change of concept of accentuation – cf. bars 222-224.
