b. 15-26

composition: Op. 27 No 1, Nocturne in C# minor

GE (→FEEE): semiquaver after the last note of the triplet

Notation in keeping with Chopin's understanding of this figure

..

In bar 15 in GE (→FE→EE), the semiquaver in the figure  was moved beyond the 3rd note of the triplet in the accompaniment, similarly in bars 17, 20-22, 24-26. This inauthentic notation, misleading for the performer, was used throughout the Nocturne.

Chopin’s fingering in FED

Teaching fingering absent

..

Chopin pencilled the two figures 1 in FED. We also apply them in the analogous figuration in bar 13.

d in GE1

d in FE (→EE) & GE2

..

The lowering d to d is missing in GE1. It is presumably an error, corrected by Chopin while profreading FE (→EE). The natural was also added in GE2 possibly according to [A].

Short accent in GE (→FEEE)

No markings in GE (→FE)

Dots in EE

..

We supplement portato dots over e2 crotchets. Dots are found in all the analogous bars, therefore we may regard their absence here as Chopin's inadvertence. The signs were already supplemented in EE.
