b. 35

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

No accidental before the 3rd semiquaver of the triplet in A (→GE1FEEE)

 raising f2 to  sharp2 in GE2

..

The version with f2 is possible both from the harmonic and the melodic point of view. However, it seems much more probable that Chopin omitted the  by mistake, as a temporary A major is the key in force in this four bar section.

b. 35

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

A slur over the dots in A

A longer slur in GE (→FEEE)

..

In our opinion, only the semiquaver triplet with dots (meaning portato.articulation in this context) is furnished with a slur  Cf. similar motifs in bars 11 and 15, and a remark related to the second slur in this bar.

b. 35-36

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

A more probable interpretation of the slur of A

A more probable interpretation of GE (→FEEE)

..

In A,  the slur is drawn carelessly and it is not certain whether Chopin intended it to embrace the second d2-eor not. Neither are we sure whether the slur was supposed to end in that bar or at the beginning of the subsequent bar. This inaccurate slur ending was also reproduced in GE (→FEEE).

For the main text we adopt the most probable interpretation of the slur in A. The earlier beginning of that slur, as visible in the editions, may be treated as a variant.

Written into FES are six signs showing the rhythmic relation between the two hands more precisely. As the source notation contains no  ambiguities here, the signs are simply learning tips for the pupil to be used during lessons. Cf. bars 38-40.

b. 35

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

..

Before the penultimate semiquaver in  A (→GE1) the  raising b flat1 to b1 is missing.  This obvious mistake was corrected in FE (→EE) and GE2.
