b. 53

composition: Op. 30 No. 1, Mazurka in C minor

No slurs in FC (→GE)

Slurs in FE (→EE)

..

We assume that Chopin added the slurs encompassing the last motif while proofreading FE. Other possibilities (less likely, according to us) could be the slurs having been added still in #A after FC had already been finished or them having been overlooked by the copyist.
