b. 23

composition: Op. 24 No. 1, Mazurka in G minor

A long accent in A

A short accent in GE and EE3

Without any accent in FE (→EE1)

..

The long accent of A was reproduced in GE  as a short one. The absence of any sign in FE (→EE1) is probably an accidental omission. The (short) accent was restored in EE3.

b. 24-25

composition: Op. 24 No. 1, Mazurka in G minor

Fingering added in FED

Fingering added in FES

No fingering provided

..

In the main text we give the characteristic fingering of FED. The entry in FES could mean the same fingering, yet it is more probable that writing one digit only, the '3', Chopin had in mind the natural fingering sequence 3-2-1.

A corrected slur in FE (→EE)

..

The original performance markings of A, misreproduced in  GE, were changed by Chopin in the proofing of FE (→EE). For our main text we take that latest (Chopin's) version.

In those bars FES has unclear pencil marks (?). Their true meaning is unknown and we can only make guesses about it.
