b. 219-220

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

2 slurs in GC (literal reading→GE)

Continuous slur in GC (contextual interpretation) & FEEE)

..

The version of GE probably results from a misinterpretation of the notation of GC – in this manuscript, b. 219 ends a great stave, and the slur, due to the discontinuation of ink flow, is poorly visible, hence it seems that it does not go beyond the last crotchet. However, the slur in b. 220 very clearly suggests continuation, which is confirmed by a continuous slur in FE (→EE).

b. 219

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

..

The  raising c2 to c2 at the end of bar appears only in FESch (written in), FE4 and EE2. The absence of this accidental constitutes an undoubted oversight by Chopin in [A] – cf. e2 and not e2 in an analogous passage in bars 91-92.

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

..

In FE1 (→FE2FE3) the 1st note in the L.H. is an A. The mistake was corrected in FESch, EE and FE4, the correct G is also in GC (→GE).

b. 220-221

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

..

In [A], there was neither  raising g3 to g3 in the last crotchet of bar 220 nor  raising e3 to e3 at the beginning of bar 221. These obvious inaccuracies were only corrected in some sources –  was added in FE4, GE and EE2, and  in FE2 (→EE,FE3FE4).

Slurs in GC

No slurs in FE

Slurs in EE

Slur in GE1

Slurs in GE2

..

The absence of the slurs in FE, unless it is a simple oversight, suggests that the slurs in GC could have been added by Chopin. They were reproduced inaccurately both in GE1 and in GE2. Most probably, the slurs added in EE are also authentic, following the line of the changes of notation, introduced gradually by Chopin here and in the analogous fragment of the exposition (see bars 93-97). We suggest the latter, as the latest and most accurate, in the main text.
(Double slurs, as the ones in the L.H. in bars 222 and 224, were used by Chopin, e.g., in the Concerto in F minor, Op. 21, 3rd mov., bars 473-480. However, one may have doubts whether the fact of doubling the signs was not an idea of the reviser of EE.)
