Rhythm

b. 15

composition: Op. 28 No. 23, Prelude in F major

Notation in A (→FC)

FE (→EE) & GE2 (→GE3)

..

In the main text we reproduce the rhythmic notation of A (→FC). The versions of the remaining sources result from an inaccurate (FE) or unskillful (GE1) reproduction thereof; in the case of GE2, it was a result of revision, probably modelled after the text of FE – see the note in the next bar.

In order for the notes on the ledger line to be visible, Chopin would make their noteheads look like short, vertical dashes, and not round dots, as it is on the stave. The bottom part of such a dash could be quite long, which confused the interpreters a few times, who would see it as an additional crotchet stem. The fifth semiquaver in each of these bars illustrates this phenomenon well. Cf., e.g. the Mazurka in B Minor, Op. 24 No. 4, b. 23
