b. 1

composition: Op. 64 No 2, Waltz in C♯ minor

No anacrusis in As & AI

Anacrusis in A (→FEGE,EE)

..

The original version without upbeat was most probably valid still at the stage of writing A, since the arrangement of signs at the beginning of this autograph proves a later addition of upbeat.

..

Shifting the  hairpin so that it starts from an upbeat, is, according to us, rather an inaccuracy of the engraver of FE, hence, in the main text we give the undoubtedly authentic sign of A. However, since an alternative possibility of Chopin's proofreading in FE cannot be entirely excluded, the version of FE, repeated in all remaining editions except for GE2no2, can be considered to be a potentially authentic variant. In turn, shortening the sign in GE2no2 is undoubtedly a revision, as a part of which the  signs in all analogous bars were unified (bars 1-2, 5-617-18 and 21-22).

b. 1-3

composition: Op. 64 No 1, Waltz in D♭ major

..

In the main text we include the fingering written in pencil in the first three bars of FED; it probably comes from Chopin.

b. 1

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

in GC (→GE) & EE2

No title in FE (→EE1)

..

While writing to Fontana in August 1839, Chopin described this movement of the Sonata as "a short finale." The omission of the convention "Finale" title in FE (→EE1) seems to be, therefore, a common oversight.

b. 1

sotto voce e legato in GC (→GE) & FE (→EE)

 & slur in Afin

..

Chopin wrote the same idea differently while preparing the Sonata for print and while writing an occasional autograph gift fragment of the finale. The version of Afin, although later, can be considered only trivia.
