Articulation, Accents, Hairpins

b. 65

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

A long accent in A

No accent in GE (→FEEE)

..

In GE (→FEEE) the long accent over a flat2 was omitted in A. This is probably a mistake.

b. 65

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

 in A (→GE)

No hairpins in FE (→EE)

..

The  present in A (→GE) disappeared in FE (→EE). As it seems unlikely that anybody introduced any corrections in that particular place, the hairpins were probably omitted by mistake.

b. 66-67

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

No accents in A (→GEFE)

Accents in EE

..

We add accents above d flat3 and c3. Those two figures end the line in A and Chopin probably simply forgot to write those two accents here, but wrote accents for the following three analogous figures in a new line. The missing accents were added in EE. Cf. the note about  slurs.

b. 69

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

A long accent in A

A short accent in GE (→FEEE)

..

The accent in A should be considered a long one, as it is clearly bigger than the short accents from previous bars. In GE (→FEEE) that difference was not made visible.

b. 69

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

Dots in A (→GEFE)

Wedges in EE

..

In the second part of the bar, EE has wedges instead of dots appearing under the slur in A (→GEFE). This is probably an arbitrary change.
