Pedalling

b. 5

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

 in GC (→GE) & FE

 in EE

..

The sources do not state clearly which quaver is affected by the  sign. One can choose between the 2nd quaver, as it is in FE and as GE interpreted the unclear sign of GC (it could have been assigned to the rest of the L.H., falling on the 2nd quaver or apply it to the 3rd, or even the 4th quaver of the bar), or the beginning of the bar, as EE interpreted the notation of FE. The piano and sound reality make us consider both versions to be possible. In the main text we reproduce the notation of the base source, i.e. FE.

b. 12

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

..

In GC (→GE) there is no  sign at the beginning of the bar. It is a patent error – all sources include a  at the end of bar 15.

b. 16

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

..

In GE1 there are no  markings in this bar – probably a result of the engraver's distraction.

b. 45

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

 in GC (→GE) & EE2

No sign in FE (→EE1)

 [] suggested by the editors

..

In the main text we include the  sign, present only in GC, and we suggest adding a , in accordance with the harmonic sense. No pedal's release asterisk is probably a result of Chopin's inattention.

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.
