The version of A (→GEFEEE)

The version of FEFr corrected by the editors

..

Franchomme described the variant of the Nocturne opening recorded in FEFr as „the change made by the author”. We correct the obviously erroneous a flat on the last semiquaver of each group to f.

b. 8

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

Lines indicating precisely the rhythm of a group of small notes in FES

No indication of synchronisation of both hands in the remaining sources

..

In A Chopin placed the small quavers more or less in the middle between the g flat3 crotchet and the c2 semiquaver,  not taking particular care to position that group in any relation to the semiquavers in the left hand. That notation was basically copied in the editions, yet in  GE, and especially in FE the group was clearly moved towards the beginning of the bar, which could in itself suggest a faulty interpretation.

b. 11

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

..

Both notes of the fifth b flat1-f2 are linked with a stem in A , which is most probably what remained from the initial single-voice version of the notation of that fragment. A also bears traces of correction of the lower note from a1 to b flat1.
