b. 22-23

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

2 slurs in FC (→GE)

Continuous slur in FE (→EE)

..

The difference in slurring can have a minimal impact on the performance in this case, hence in the main text we give the version of the principal source, which is FC (→GE).

b. 23

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

No indication in FE (→EE)

in FC (→GE)

..

The  indication could have been entered into FC by Chopin or overlooked by the engraver of FE.

b. 24

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

..

The sources do not include a  restoring b on the 3rd beat of the bar, which means that this accidental was also absent in [A]. In the main text, we correct this oversight, patent in this harmonic context and generally fairly typical of Chopin.

Long accent in FE

Short accent in FC (→GE) & EE

..

According to us, the long accent visible in FE corresponds to the notation of [A], hence we give it in the main text. We believe that the short accents of both FC (→GE) and EE resulted from an inaccurate reproduction of their respective bases.
