Pitch

b. 48-49

composition: Op. 24 No. 2, Mazurka in C major

Without a slur in A (→GEFEEE1EE2)

A slur in EE3

..

The slur added in EE3, probably by analogy to the slur added in bars 16-17 in EE, is certainly inauthentic.

b. 53

composition: Op. 24 No. 2, Mazurka in C major

Without a dot in A (→GE)

A dot in FE (→EE)

..

The third staccato dot in this bar, appearing in FE (→EE), is most probably a mistake. Notes on which short slurs begin are contrasted in A with staccato-marked notes ending the slurred crotchet pairs. The FE dot would disturb that regularity, with the detriment to the clarity of the entire transition section (bars 52-56).

 and an accent in A

 in GE (→FEEE)

..

In  A the accent mark and  are written one on top of the other, so it is not clear whether both should be taken into consideration or whether one was meant to replace the other. In GE (→FEEE) that notation was understood as replacement of the accent with . However, as there are no visible attempts to remove any of the marks, perhaps Chopin could mean superimposing one on the other, the effect known from numerous combinations such as . Therefore we give both marks in our main text.

b. 57

composition: Op. 24 No. 2, Mazurka in C major

..

There are traces of corrections at the beginning of this bar in A. The note A flat1 was entered by Chopin instead of a deleted chord, most probably the same as the two further chords .

b. 64

composition: Op. 24 No. 2, Mazurka in C major

Sixths in A (→GE)

A chord in GE (→EE)

..

Initially, the 2rd and the 3rd crotchet were e flat-a flat-c1 triads in A. Then Chopin erased both a flat notes and this was the version that appeared in GE. The note a flat reappears in FE (→EE), but only on the 2nd beat. This is probably the result of Chopin's correction in FE.
