b. 3-7

composition: Op. 28 No. 15, Prelude in D♭ major

Fingering written into FED

Fingering digit written into FES

No teaching fingering

In the main text we give the undoubtedly Chopinesque fingering entered into FED in b. 3 and 7. The key element of that fingering – the 4th finger for the g2 minim – was also added in FES. The 4th finger crossing over the 5th (typical of the Chopinesque fingering) and the 4th finger slipping down from a black to a white key were also indicated in analogous b. 22 and 78. See also b. 14, 15-16 and, e.g. the Sonata in B Minor, Op. 35, 3rd mov., b. 31 or the Nocturne in B Major, Op. 32 No. 1, b. 37.
According to us, indicating the 1st finger twice means that the notes should be performed by the R.H., but it is not explicitly marked (as it was done, e.g. in b. 9); they could also be performed by the L.H. However, the following reasoning is an argument in favour of the R.H. – all notes with beams on the bottom stave should be generally performed by the L.H., which, in this context, implies this very fingering, which, therefore, would not need to be marked at all.

The last R.H. quaver in GE is an erroneous e1 note – the engraver probably applied the pattern from the previous bars, in which the outer notes of the 2nd and 4th triplets are at the same pitch.

In the main text we include the fingering entered into FESch, which could be coming from Chopin. Similar situations are in b. 6-7, 10, 12 and 15.
