b. 4

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

Without an accent in A (→GEFE)

A long accent added in EE

..

In EE, a long accent was added under b flat2, probably on the basis of the sign visible in FE in analogous bar 28.

b. 4-5

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

Slur end in A

GE (→FEEE)

..

The extent of the slur is not precisely marked in A. In GE (→FEEE) the slur was read as ending in bar 4. In our opinion, it is more probable that Chopin intended it to reach the beginning of bar 5 (cf. the remark at the end of bar 2).

b. 5

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

A long accent in A (→GE2) and FE

A short accent in GE1 and EE

..

The accent over a1 is doubtless a long one in A; this is testified by the change made in GE2 (probably after a repeated analysis of A). The sign in FE is not quite clear, yet it resembles a long accent more than a short one. In spite of that, EE has a short accent over the note in question.

b. 6-7

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

A more probable interpretation of the slurs of A

A less probable interpretation of A (→GEFEEE)

..

In the sources, bar 7 begins a new line of text; in such situations it is difficult to decide in Chopin's autographs whether the slur is to be treated as a new sign or a continuation of the previous one.
