b. 212

composition: Op. 42, Waltz in A♭ major

..

The sign added in FED, a vertical line, probably underlines the necessity to separate the ending unisono phrase from the following refrain.

b. 212

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

..

FE has a as the bottom note of the 1st crotchet in the bar. This patent mistake was corrected in the base text to EE. GC (→GE) also includes the correct f.

b. 212-214

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

7 slurs in GC

6 slurs in FE (→EE) & GE2

3 slurs in GE1

..

These bars, as well as a few next ones, are a characteristic example of Gutmann's inaccuracy as a copyist. The slurs are drawn so inaccurately that the engraver of GE1 simply omitted a few of them, not knowing what to do with them. Our suggestion of their interpretation is only a certain idea of the actual notation. We do not try finding sense in this slurring – there is no doubt that Chopin's intention were regular, three-crotchet-long slurs, conveyed by FE (→EE) and correctly interpreted in GE2.

b. 212-213

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

Slur in A, contextual interpretation

No slur in GE (→FEEE)

..

In A there is only an ending of the slur in bar 213 (on a new page). Similarly as in bars 205-207, we assume that it demonstrates that the composer's intention was to embrace with a slur the preceding phrase or motif, which in this case comes down to emphasising the unexpected e-f bass' step.

b. 212-213

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

Slur to bar 213 in A & contextual interpretation of FE (→EE)

Slur only in bar 212 in GE

..

In spite of the clear extended slur of A, in GE the slur does not end on the last note in bar 212, which certainly does not correspond to Chopin's intention. FE (→EE) repeated the slur of GE in bar 212 (the last on the page), yet in bar 213, on a new page, a slur reaching the minim was added, as if it were an ending of the previous slur. The added slur is probably a Chopin one, and the ambiguity of notation is a result of a careless implementation of the proofreading, hence we assume that the slurs designate one slur, as in A.
