Slurs

b. 109-110

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

Two-bar slur in GC (→GE)

No slurs in FE1 (→FE2)

Slur in bar 110 in FE3 (→FE4) & EE1

Two slurs in EE2

..

In GC (→GE) one slur embraces the part of the L.H. in both bars. The shorter slur, including only the reminiscence of the initial motif of the Sonata in bar 110, added by Chopin in the proofreading of FE3 (→FE4) and in the base text to EE, is certainly later and – according to us – it can be considered to be the final version.
The compiled version of EE2 cannot be authentic.

b. 116

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

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).

b. 117

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

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).

b. 125-126

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

4 slurs in GC & FE (→EE)

2 slurs in GE

..

In GE, the L.H. slurs encompass the entire bars. It possibly results from a misinterpretation of the hardly legible writing of GC (intermittent ink flow).

b. 127-132

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

2 new slurs in GC (→GE)

No new slur in FE1 (→FE2)

1 slur in FE3 (→FE4) & EE

1 new slur suggested by the editors

..

In the main text we suggest a slur in which we assemble the most reliable elements of source versions – musically and pianistically natural beginning of the phrase in bar 129 after GC (→GE) and a non-separated slur in bars 130-131 after the Chopinesque proofreading of FE3 (→FE4) and base text to EE.
