b. 32

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

A beam in  A (→GE)

A flag in FE (→EE)

..

We give the certainly authentic notation of A (→GE). It seems very unlikely that Chopin intentionally changed that notation in the proofing of FE (→EE).

b. 32

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

 in A (→GE2)

A shorter dynamic mark in GE1 (→FE)

 added in EE

..

The hairpins  clearly written in A  were inaccurately reproduced in GE1 (→FE). That shorter mark was then arbitrarily supplemented in EE by adding  . The notation of A was restored in GE2

b. 32

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

A more probable interpretation of the slur written in A

A less probable interpretation of A (→GEFEEE)

..

The slur in A breaks off high above the notes; therefore, it is not clear where exactly Chopin intended it to end. We adopt the interpretation that is more natural in this context, both from the articulation and the phrasing point of view.

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

 in A

No hairpins in GE (→FEEE)

() – the editors' suggestion

..

The omission  of    in the editions is probably due to oversight on the part of the engraver of GE (→FEEE). However, as Chopin's correction of GE1 cannot be ruled out we suggest a variant proposal with the hairpins in brackets.

b. 32

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

..

We add cautionary naturals before b flat1 in the 2nd demisemiquaver triplet and e flat3 in the last one. The first sign was added as early as FE (→EE), probably by Chopin's request, the second one in EE.
