b. 49-52

b. 49

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

D flat in A (→GEFEEE)

An octave sign written into FED

..

The sense and authenticity of this sign in FED is doubtless, yet due to the much more powerful and longer-sounding bass register of contemporary pianos this variant may only be used with utmost caution.

b. 49

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

A long accent in A

A short accent in GE (→FEEE)

..

Reproduction of the notation of A in the editions is inaccurate in two aspects: Chopin's long accent was reproduced as a short one and the marks  and > were tied together, which may suggest the limited application of  only to the right hand.

b. 49-50

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

Dynamic markings in A (→GEFEEE)

 added in FED, FEJ, FES

 and  in FEFr

The editors' proposal

..

We perceive the indication  in bar 50, added by Chopin in the three teaching copies and written into FEFr, to be part of a definitive change of the dynamic concept in several fragments of the Nocturne (cf. bars 25-26, 45-46, 52). The   noted by Franchomme in FEFr naturally supplements that change.

b. 49-50

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

Without an entry from the teaching copy

A complete entry in FES

A possible interpretation of the entry

A less possible interpretation of the entry

..

The meaning of the slur entered into FES is not clear. One of the possible interpretations is a variant in the form of a run filling the octave leap of the melody. If we take into account the hardly legible sign in bar 50 and perceive it as the digit 8, we may conclude that the run goes up to c4.
