b. 64-65

composition: Op. 50 No. 3, Mazurka in C♯ minor

Separate slurs in AI

Continuous slur in AF (→FEEE) & GE

..

The division of the slur in AI could have resulted from the uncertainty about the combination of b. 64-65 and about the final shape of the melody in b. 65-68 – in the initial version of the L.H. part, there was no transitional F note, while in the alternative version of the melody, b. 65 opens with a repeated e2. Therefore, the combination of b. 64-65 in the rejected versions is not as smooth as in the final one.

b. 65-67

composition: Op. 50 No. 3, Mazurka in C♯ minor

AF (→FEEE) & GE (main version in AI)

Alternative version in AI

..

In b. 65 and 67, there are two variant versions of the R.H. motifs in AI. Eventually, Chopin used the idea that was written first.

b. 65

composition: Op. 50 No. 3, Mazurka in C♯ minor

No slur in AI & GE

Slur over chords in AF (→FEEE)

..

The missing slur in GE seems to be an oversight of the engraver – in this edition L.H. slurs appear from b. 66, opening a new line, yet both slurs in b. 64-65 were overlooked.

b. 66

composition: Op. 50 No. 3, Mazurka in C♯ minor

..

In AI one can see the deleted initial form of the accompaniment – c and 2 g-c1-e1 chords – and the added final version.

b. 66-75

composition: Op. 50 No. 3, Mazurka in C♯ minor

..

In these bars, AI does not contain a single L.H. motivic/articulation slur, which results from the working nature of this autograph – cf. b. 64-65.
In AF the slurs in b. 70-71 and 73-75 (as well as 65) illustrate how inaccurately written Chopin's slurs could be – their range does not raise any doubts here only thanks to the rests surrounding the motifs encompassed by the slurs.
