Dot & slur suggested by the editors

b. 124-125

composition: Op. 30 No. 4, Mazurka in C# minor

2 slurs in FC (→GE)

Continuous slur in FE (→EE)

..

Both versions of slurring are musically justified – the slur of FC begins together with the new four-bar section, while the slur of FE emphasises the fact that the new section derives from the ending of the preceding phrase. We give the slurs of the principal source.

b. 125

composition: Op. 30 No. 4, Mazurka in C# minor

poco stretto in FC (→GE)

calando in FE (→EE)

..

The differing performance markings of FC and FE were independently introduced by Chopin both in the copy and in the stage of proofreading FE (or in the basis for it) – see the note on the filiation of the Mazurkas. In the main text we give the version of the principal source (FC), but the second version may be regarded as an equal option.
