No slur in GC (→GE) & FE1 (→FE2)

Slur in FE3 (→FE4) & EE

The slur over the final motif is undoubtedly a Chopin addition in the proofreading of FE3 (→FE4) and in the base text to EE.

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

End of slur in GC, literal reading

End of slur in GC (contextual interpretation→GE) & FE3 (→FE4,FE5) & EE

..

In GC, same as in bar 16 (bar 70 is only marked as its repetition), the end of the slur can be interpreted in two ways. In the main text we give a more likely, conventional interpretation of this detail, present in all editions – only in FE1 (→FE2) the slur in bars 77-78 was entirely overlooked.

b. 81

composition: Op. 42, Waltz in A♭ major

d1-e1 in FE0 (→FE,FEGGE1)

d1-e1-g1 in EE & GE2 (→GE3)

..

The d1-e1 second featured in FE and GE1 is the original version, which is proven by the comparison with the remaining four analogous places in bars 49, 113, 173 and 269. In three out of five of these places, Chopin added to it the gnote in FEG (→GE). In EE the completed version with the d1-e1-gis present in all five places, which also proves Chopin's proofreading. Therefore, the fact of leaving the original version of the discussed bar in FE and GE1 must be considered as Chopin's oversight.

b. 81-87

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

6 different slurs in GC

No slurs in FE

7 shorter slurs in EE

4 longer slurs in GE1

5 longer slurs in GE2

7 longer slurs – our suggestion

..

Both versions of slurring appearing in the sources may be authentic, although it does not seem that Chopin hesitated how to mark these bars. The difference results rather from an inaccurate notation, both in [A] (→GCGE) and in the base text to EE. Settling this kind of doubt can be difficult, even if we dispose of the autograph – cf. the Mazurka in G minor, Op. 24 No. 1, bar 21. In the main text, in all seven bars we give slurs embracing entire bars, in accordance with the notation of GC in the vast majority of the cases (five out of six). The version of EE can be considered to be an alternative, equivalent suggestion (in bars 81-84 it offers a kind of an accent on each strike: strong beat of a bar, beginning of the slur, a written out accent; it should not blur the natural character of this delicately swinging figure).
