composition: Op. 25 No 7, Etude in C♯ minor

Dotted rhythm in GC (→GE) & EE

Even semiquavers in FE

..

The authenticity of the dotted rhythm in GC (→GE) and EE does not raise any doubts. The equal semiquavers of FE may be considered as a result of inattention of the engraver or misunderstanding of the handwritten base text, yet the version can be also a result of Chopin's correction, introduced still in the manuscript or proofreading of FE. As one of the traces of possible changes performed in print, one can consider the too long slur, adjusted to the note being closer to the bar line than the visible g semiquaver.

Demisemiquaver in GC (→GE)

Semiquaver in FE & EE

It is unclear how the difference in the rhythm in this place was created, however, none of these two versions seems to be erroneous. The notation of EE indicates a possibility of the engraver's error – the bsemiquaver is placed closer to the bar line than the g semiquaver, therefore, it is possible that in the base text to EE the rhythm was the same as in GC. It also cannot be excluded that the additional dot and beam were added in GC by Chopin, although the graphical image of the notation rather does not confirm it. Due to the above ambiguities, in the main text we give the double dotted rhythm, present in the base source (GC).
