b. 47-48

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

 in GC & FE (→EE)

No sign in GE1

Longer  in GE2

..

No  in GE1 is almost certainly an oversight. The sign was added in GE2, in a form which, however, deviates from the notation of GC.

b. 48

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

Slur over triplet in GC

Slur over whole bar in FE (→EE) & GE

..

The slur in GC is a typical "triplet" slur. Embracing with it the entire bar in GE is most probably a revision inspired by the slur in bar 44. However, the identical slur in FE (→EE) can be a result of Chopin's correction in [A].

b. 49

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

Half-bar pedal in GC & GE2

No pedal in FE (→EE1)

Whole-bar pedal in GE1 & EE2

..

In the main text we give the pedalling of GC. GE1 reproduced it inaccurately, which was corrected in GE2, yet then repeated in EE2.

b. 49

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

No sign in GC (→GE)

Arpeggio sign in FE (→EE)

..

The arpeggio sign is already present in FE1, based directly on [A], and almost certainly uncorrected by Chopin. This suggests the absence of the sign in GC (→GE) is probably an oversight. Similarly in bar 65.

b. 49-50

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

 in GC (→GE)

Longer  hairpin in FE (→EE)

..

In the main text we reproduce the notation of the principal source, i.e. FE (see General Editorial Principles and the characterisation of FE4).
