b. 51

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

..

We add a cautionary  before c2.

The initial notation of A (  for c flatin bar 52)

Naturals added in A 

GE (→FEEE)

..

A has naturals before the 5th note from the end in bar 51 and the 3rd note of bar 52, which makes  them, respectively, c3 and c4. These naturals were most probably added by a foreign hand (perhaps the reviewer of GE1). Initially, A had only  before the 3rd note of bar 52. Therefore we give that initial version as the version of A, disregarding the improbable change, and we also supplement the omitted   in bar 51. The editions have the unquestionable text with the two flats (c3 and c4) in those places. Cf. bar 55.

The slur in A

GE (→FEEE)

..

The slur over the run in bar 51 clearly reaches the first b3 of bar 52 in A. Nonetheless, it was reproduced in the editions as not extending beyond bar 51.

Fingering entered into FED

No teaching fingering provided

..

The numbers entered into FES probably mean the same fingering as that written out in by Chopin in FED.

con forza in A (→GEFEEE)

Deleted in FES and removed from FEFr

Probable reading of the entry in FEJ

The variant proposal of the editors

..

The indication con forza occurring in A (→GE>FEEE) was deleted by Chopin in FEJ and FES, and removed by Franchomme from FEFr. We perceive those actions as the part of the radically altered concept for the dynamics in that part of the Nocturne (see bars 49-50). We also suggest the possibility of taking into account the somewhat unclear entry in FEJ.
