Issues : Dotted or even rhythm

b. 21

composition: Op. 50 No. 1, Mazurka in G major

Staccato quaver & semiquaver in A1

Quaver & semiquaver in FE (→EE)

2 quavers in GE

..

There are no reasons to consider the version of GE to be erroneous: the change of rhythm with respect to the remaining sources is confirmed by the complementary slur. On the other hand, deprived of insight into [A2], one cannot state whether Chopin replaced therein a previous version or whether he simply wrote another one, which does not give us grounds to consider the previous one to be rejected. Due to the above reason, we consider both possibilities equal.
The missing staccato dot in FE (→EE) is most probably an oversight.

composition: Op. 50 No. 1, Mazurka in G major

Dotted rhythm in A1 (→FEEE)

Quavers in GE

..

The quavers in the L.H. top voice might be a mistake of GE, since due to the parallel movement, the voices are not independent. In the entire Mazurka a similar combination of L.H. quavers with R.H. dotted rhythm appears only twice, in b. 47 and 54. In both cases the voices co-create the polyphonising texture and are clearly independent.
