b. 19-20

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

A phrase mark (slur) in A

A distorted slur in GE (→FEEE)

..

The slur in A is written with a large stroke, but its extent is doubtless. The fact that the engraver of GE interpreted it as covering the whole bar, not a motif, is a glaring example of the manner adopted for manuscript reading in GE (see the characteristics of that edition).

b. 20

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

e flat1 in A (→GE>FE) and EE3

f flat1 in EE1

..

EE1 has  f flat1, obviously erroneous, as the 4th semiquaver The rule whereby the 2nd and the 4th note of any particular accompaniment figure must be the same is strictly observed in the Nocturne. The error was corrected in EE3.

..

In A Chopin forgot to repeat the tie sustaining a flat1 in the new system. This most probably caused an error in GE1, where that tie is missing. The error was corrected, probably by Chopin, in FE (→EE), it was also rectified in GE2.

GE2 has the  mark slightly moved to the left. This is the most clearly visible one of the change that occurred in connection with the change of the printing technique in later printing runs of GE1
