b. 36

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

staccato dot in A

Absence of any mark in GE (→FEEE)

The editors' suggestion (variant)

..

The dot in A may be a staccato dot, but as we cannot be sure, we give it in parentheses to be applied at the performer's discretion.

b. 37

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

..

In A the quaver flag is missing in the 3rd quaver of the bar. Chopin's obvious mistake was corrected in GE (→FEEE). It might have been noticed by Chopin himself, but it is more probable that it was the reviewer of GE that made the correction

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

Possibly a long accent in A

Short hairpins in  GE (→FEEE)

..

The dynamic mark in A resembles a long accent. Yet, taking into account the marking of an analogous phrase two bars earlier, it can be considered diminuendo hairpins, and was interpreted as such in GE (→FEEE). Anyway, the difference between the two interpretations is more academic than practical, both from the graphic and the performance-related point of view.

A probably has a long accent here.

A short accent in GE (→FEEE)

..

The shape of the accent in A makes it resemble a short accent  (a relatively wide angle between the arms), but it has the size of a long accent. The syncopated longer rhythmic value of the accented note makes us believe it was meant to be a long accent, yet the editions have a short accent here.

A tie sustaining c sharp2 in A (→GE) and FEFr

No tie in FE (→EE)

..

The tie sustaining c sharp2 was probably omitted in FE (→EE) by the engraver. It was added again in FEFr.
