Rhythm

b. 28

composition: Op. 27 No 2, Nocturne in D♭ major

The main version (AGEFEEE)

A variant recorded in FEFr

A variant written into FED

..

The additions in FED and FEFr may be regarded two versions of the same musical idea - syncopations in FEFr show the rubato performance of the quavers in FED.

b. 32

composition: Op. 27 No 2, Nocturne in D♭ major

A beam in  A (→GE)

A flag in FE (→EE)

..

We give the certainly authentic notation of A (→GE). It seems very unlikely that Chopin intentionally changed that notation in the proofing of FE (→EE).

b. 33

composition: Op. 27 No 2, Nocturne in D♭ major

..

At the end of the triplet tie in EE the demisemiquaver beam was accidentally omitted.

We add [3] to make the rhythm of that figure more clear.

b. 34

composition: Op. 27 No 2, Nocturne in D♭ major

..

The sources differ with regard to the form of the beam in the 2nd half of the bar. Both the graphic detail differentiating GE from the other sources (the placement of the demisemiquaver beam) and the easy to correct mistake of FE (→EE) – the last sixth having the value of a quaver  – have no bearing on the interpretation of the text.
