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

e flat1 in A (→GE>FE) and EE3

f flat1 in EE1

..

EE1 has  f flat1, obviously erroneous, as the 4th semiquaver The rule whereby the 2nd and the 4th note of any particular accompaniment figure must be the same is strictly observed in the Nocturne. The error was corrected in EE3.

b. 21

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

A (→GEFEEE)

A variant given in FEFr

..

The variant written by Franchomme into FEFr displays all the elements of Chopin's style. It is not unlikely that a zigzag visible in FED between the grace note b double flat1 and the following f flat2 means a similar ornamental phrase.
