b. 24

composition: Op. 30 No. 1, Mazurka in C minor

Slur to g in FC (→GE)

Slur to b in FE (→EE)

..

The fact that the slur of FE (→EE) runs only to the b quaver must be an inaccuracy.

issues: Inaccuracies in FE

b. 24-25

composition: Op. 30 No. 1, Mazurka in C minor

No markings in FE (→EE)

Slur & dot in FC (→GE)

..

The slur and staccato dot were most probably added to FC by Chopin (together with the pedal marks in this bar), and we include them as such in the main text.

b. 25

composition: Op. 30 No. 1, Mazurka in C minor

No mark in sources

Long accent suggested by the editors

..

In the main text we add a long accent over the a1 minim after the marks added by Chopin to FC in analogous bars 17, 19 and 27. The reason for this very likely oversight by Chopin could have been the fact that the discussed bar is at the end of a page.

b. 25

composition: Op. 30 No. 1, Mazurka in C minor

  in FC (→GE)

b. 26

composition: Op. 30 No. 1, Mazurka in C minor

No sign in FE (→EE)

in FC

..

As in bar 18, in the main text we give the  hairpin entered almost certainly by Chopin into FC. In GE the mark was clearly extended, which can interfere with the performance manner intended by Chopin.
