b. 275-276

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

in GC

No sign in FE (→EE) & GE

..

The  hairpin was probably added in GC by Chopin. The missing sign in GE is certainly a mistake of the engraver who perhaps was not sure where to put the sign.

b. 275

EE1 has erroneously g instead of a as the inner note of the last L.H. chord. The mistake was corrected in EE2.

Pedalling in GC (→GE)

Only  in FE

Pedalling in EE

Our variant suggestion

..

It is not clear how the difference in pedal markings arose between GC (→GE) and FE. Possible are both the oversight of  by the engraver of FE and the mistaken placement of the sign by the copyist. Chopin also could have crossed  out in [A] after GC had been prepared. Considering the authenticity and chronology of the two source versions as uncertain we suggest a variant solution in the main text.
The sign in EE, despite of its apparent accordance with GC, seems to be a reviser's addition – the sign is different in form from other similar signs.

b. 276-277

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

Slur up to beginning of bar 277 in GC & FE (contextual interpretation)

Slur up to beginning of bar 276 in GE

Slur up to end of bar 276 in FE (literal reading→EE)

..

Leading the slur in GC until bar 277 is obvious, in spite of the lack of the slur's ending in a new line – in bar 276 (at the end of the line) both the slur and the tie of bgo far beyond the bar line and none of them is finished afterwards, which points to an oversight of the person who was writing. The fact of shortening the slur in GE must be then considered a missed revision. In FE the situation is analogous to GC – both curved lines, reaching the end of the line in bar 266, suggest continuation, which, however, does not follow (FE4 finished the tie). In spite of this, the engraver of EE interpreted each of these curved lines differently – the tie is led to bin bar 277 but the phrase mark only to bar 266.
From the practical point of view, all three notations mean the same thing.

b. 281

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

No sign in the sources

Our alternative suggestion

..

The suggested complement to the pedalling visualizes the fact that the possibly authentic lack of  following the  sign in bar 276 does not indicate the pedal should be held up to the end of the Scherzo.
