b. 12

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

e(1) in Afin

e(1) in GC (→GE) & FE (→EE)

..

The version of Afin, with a written cautionary  before e1, is certainly authentic, however, according to us, it can be considered to be an equal variant with respect to the published version. Afin was performed with a visible haste, without taking care of the accuracy of notation, whereas its fragmentary character excludes its use as a score to perform the music written in it.

b. 59

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

..

Chopin added the cautionary flats before c-c1 in GC (→GE). They were added – most probably on the basis of GE – also in EE2.

b. 61

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

..

We do not include the unnecessary cautionary flats before the 9th quaver. Chopin may have written them to differentiate this triplet from the first one in this bar (if it is not a mistake).
