b. 2

composition: Op. 27 No 1, Nocturne in C# minor

..

We remove the digits 6 with which the sextuplets are marked in the sources also in this bar. This may be the result of a literal reading of the abbreviation that Chopin used in the autograph to mark the repetition in bar 2 of the rhythmic group from bar 1.

A more probable interpreta­tion of the slur in A

A less probable interpreta­tion of A (→GEFEEE)

..

The slur in A ends in a manner that allows for two interpretations. In GE (→FEEE), that slur was considered to end on the last note of bar 2. In our opinion, it should extend to a flat1 at the beginning of bar 3.

No slurs in the left hand in A (→GEFE)

The slurs arbitrarily added in EE

..

In EE, slurs were added in the left hand in those bars. This is definitely the editor's revision that was supposed to emphasize that slurring was binding throughout the entire Nocturne. EE also introduced similar revisions in bars 16 & 31.
