Rhythm in JC & EF

Rhythm in PE

..

The dotted rhythm at the beginning of the 3rd beat of the bar in JC and EF is most probably an earlier version in relation to equal semiquavers of PE, which we give in the main text.

b. 26

composition: Op. 30, Mazurka in D♭ major

Quavers in FC (→GE)

Dotted rhythm in FE (→EE)

..

None of the sources bears traces of changes here, which makes it impossible to determine its cause. A mistake seems more likely in FC – it is easier not to write a dot and a beam than to write them without any reason. However, this does not discredit the version of FC, since Chopin could have changed the rhythm in [A], reviewing it before handing it over to Fontana. In the main text we give the rhythm of FC, being the principal source; however, we regard the version of FE as equal.

b. 27

composition: Op. 10 No 12, Etude in C minor

Dotted rhythm in A

Semiquavers in FE (→GE,EE

..

Chopin changed the rhythm of A while proofreading FE (there are visible traces of this change). The withdrawal from the rhythmic underlining of the topmost note of the passage may be related to a minor change in the Etude's concept, revealed also in increasing its tempo. See also bars 30 and 32.

In bar 29, it is hard to determine whether the rhythms of JC and EF are authentic. It cannot be excluded that one of them (or even both) are a result of a misunderstanding of the notation of [AI], which could be ambiguous, e.g., due to corrections. In the main text we give the rhythm of PE, compatible with the rhythm of analogous motifs in bars 25 and 27. We also consider the phrasing of the third sequence in bars 29-30, which emphasises this rhythm.

Even quavers in JC and EF are almost certainly the original version of the rhythm in this place.
