b. 14

composition: Op. 35, Sonata in B♭ minor, Mvt III

Quavers in GC & FE (→EE)

Dotted rhythm in GE

..

The dotted rhythm in GE is most probably either a mistake or revision, perhaps resulting from the conviction that the notation of GC is inaccurate – in the same figure there are no dots extending the first octave of the bar. Similarly in bar 68.

composition: Op. 10 No 9, Etude in F minor

Quavers in AI

Dotted rhythm in A (→FEGE,EE)

..

The rhythm of AI is undoubtedly the original version of this motif, most probably changed at the time of writing A. It is indicated by gaps between the notes of this motif, corresponding to equal quavers.

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.
