b. 115

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

..

Similarly as in bar 107, in GC, FE1 (→FE2FE3,EE1) there is no  raising b to b. The sign was added in GE, FE4 and EE2.

b. 115

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

..

In GE, there is no crotchet rest for the lower voice on the last beat, which could be the engraver's oversight (see the complete record in bars 112-114) or a revision – GE omitted the corresponding rest also in the analogous bar 107.

Slur in GC (→GE) & EE2

No slur in FE (→EE1)

..

Similarly to bar 108, the absence of the L.H. slur in FE (→EE1) could have been an oversight by the engraver of FE (rectified in EE2) or Chopin added this slur in #FC (→GE).

No mark in GC (→GE) & FE1 (→FE2EE)

Long accent in FE3 (→FE4)

..

The accent over e1 is undoubtedly a Chopinesque addition in the proofreading of FE3 (→FE4).

Pedalling in GC & GE2

Pedalling in FE (→EE)

Pedaling in GE1

..

In GC the sign is placed in the middle of the first half of the bar, so that it seems to refer to the e1 quaver. Such a placement is most probably inaccurate, and in GE1 the sign was shifted farther left, which is plainly wrong. GE2 restored the GC version. In the main text, we give the undoubtedly correct version of FE (→EE).
