b. 14

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

Annotation in FED, probable interpretation

No teaching fingering

..

It is unclear what the addition in FED under the 12th and 13th semiquavers means. According to us, it is most probably a semiquaver beam; in this context, it has only one meaning, i.e. the marked notes should be played by the L.H. This is meant to facilitate the performance, although it is not obvious at first glance – instead of eliminating the tenth leap, it allows to keep the R.H. in a position that enables its performance. We do not offer this interpretation in the main text due to it being uncertain.

There is no  raising b3 to b3 in A (→FE). The obvious inaccuracy was corrected in FC (→GE) and EE.

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.

Slur to  f2 in A (→FEEE)

Slur to c2 in FC (→GE)

..

The shorter slur is an inaccuracy of Fontana, who considered the slur to be related to the triplet marking.

No fingering in A (→FE,FCGE)

Fingering in EE

..

Nothing indicates that the fingering in EE could have come from Chopin although it is probably in line with Chopin's one here – cf. bar 1.
