b. 89-97

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

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

Notation in keeping with Chopin's understanding of such figures

..

In bars 89, 91-95 & 97 GE (→FEEE) moved the semiquaver in  beyond the 3rd note of the triplet in the accompaniment, contrary to Chopin's understanding of that figure.

b. 90

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

No sign in GE (→FE)

 in EE

..

The sign  added in EE is certainly an arbitrary revision introduced on the basis of similar passages.

We add a cautionary natural before e2.

b. 92

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

No dynamic markings in GE (→FE)

added in EE1 (→EE2)

added in EE3

..

Both added in EE1 (→EE2) and in EE3 are definitely arbitrary additions introduced by the revisers of EE copying authentic signs from similar bar 9. However, in this passage they are clearly unjustified for they do not fit different dynamic shape of the phrase in neighbouring bars: in bar 91, and accents in bar 93.

b. 92-93

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

No tie in GE (→FEEE)

Tie added in FED

..

The crotchet b1 in bar 92 is not tied to bar 93 in GE (→FEEE). A comparison with the analogous bars 25-26 suggests a possible oversight of the tie. The sign pencilled by Chopin into FED confirms this assumption.
