Slurs

b. 52-53

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

Slurs in A (→GE)

A prolonged slur in FE (→EE)

The editors' suggestion - without the 'triplet' slur

..

In A (→GE) the articulation-phrasing slur embraces only bar 52. When correcting FE (→EE), Chopin extended it to reach the half of bar 53 and we give that longer slur in the main text.

There is also a slur above the demisemiquaver triplet in the sources. The addition of a long phrasing slur in the proofing of FE reduced the 'triplet' slur to a purely formal function (cf. General editorial principles p. 16), so we remove it from the main text.

b. 54

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

The slur in  A

GE (→FEEE)

..

In A, the slur clearly begins over the second quaver of the bar. The earlier beginning of that slur in GE (→FEEE) is probably a result of a routine reading of the extent of that sign by the engraver of GE1. However, the fact that no corrections were made in FE or the teaching copies may point to Chopin's acceptance of the longer slur.

b. 54

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

A slur in A (→GE)

FE (→EE)

..

The slur in FE (→EE) is certainly erroneous - most probably, the engraver (getting his bearings on the basis of the grouping of notes between the rests) embraced the triplet and one note towards the rest with the slur, but he mixed up the directions.

b. 55

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

The slur in A (→GEFE)

 
..

In EE, the slur in the 2nd half of the bar was shortened, its beginning moved by one semiquaver.

b. 56

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

The slur in A (interpreted in context)

GE1 (→FEEE)

..

The right end of the slur in A fails to embrace the last note of the motif, and this is how that fragment was interpreted in GE1 (→FEEE). In GE2, the slur was made longer so as to include the note not originally embraced but only pointed to by its right end. In our opinion that latter interpretation is probably consistent with Chopin's intention.
