b. 257-261

composition: Op. 42, Waltz in A♭ major

No slurs in FE0

One slur in FE1

Two slurs in EE

Three slurs in GE

..

Chopin introduced three slurs in bars 257-261 in FEG (→GE). It is hard to assume whether the lack of the last slur in EE is a result of Chopin's oversight or a possible error of the engraver. FE has one long slur, most probably added by Chopin in the proofreading.

b. 257-261

composition: Op. 42, Waltz in A♭ major

 
 
..

In FEG Chopin did not write the ending of the slur in a new line (bar 261), yet the slur written in the previous great stave clearly suggests continuation and in GE it was understood in that way. EE omits the entire slur in bars 260-261, which can be explained by Chopin's oversight or the engraver's mistake.

b. 257-258

composition: Op. 35, Sonata in B♭ minor, Mvt II

Two  signs in GC (→GE)

Two-bar  in FE (→EE)

..

One  sign in FE (→EE) is most probably an arbitrary decision of the engraver of FE.

b. 257-260

composition: Op. 21, Concerto in F minor, Mvt I

Slur in bars 257-258 in A

4 slurs in GE (→FEEE)

..

The absence of three out of four slurs under the motifs in the L.H. in A must be considered Chopin's neglect (the slurs are still present in bars 261-262). Therefore, in the main text we include the slurs added in GE (→FEEE), although it is not absolutely certain whether it was Chopin's proofreading. See also bars 259-260.
