b. 15

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

 from the 2nd semiquaver in A, FE (?) and EE

 from the 1st semiquaver in GE (→FE ?)

..

The extent of   in A matches the authentic phrasing. In GE the sign begins earlier, which Chopin perhaps corrected in FE (→EE).

b. 15

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

 before the last but one semiquaver in A (→GE)

Three other naturals in FE

 removed before f2 in EE1

Corrected versions of FEFr and EE3

..

The edited text is the indisputable version of A (→GE); also EE3 and FEFr have the correct text. The version of FE (→EE1) is most probably erroneous – cf. analogous bar 55.

b. 16

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

 in A

GE (→FEEE)

..

In our opinion, the hairpins in A are written inaccurately - the sign begins before the notes, suggesting that the crescendo is a continuation from the previous bar, which does not find any musical justification. The sign visible in the editions matches more naturally the beginning of a new four-bar section.

b. 16-17

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

Wedges in A

Dots in GE (→FEEE)

..

In motifs ending on the highest note Chopin furnished those notes with wedges in A. In GE all those signs were interpreted as dots.

b. 16-17

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

Literal reading of the slurs of A

Slurs in GE (→FEEE)

..

When read literally in A, the slurs in the indicated place and at the transition point between bar 16 and bar 17 do not reach the last notes in three-note motifs. This was recognized as an instance of inaccurate notation and correctly interpreted already in GE.
