b. 8-25

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

One-bar slurs in AI, A & GE2op (→GE3op)

Two-bar slurs in FE (→EE,GE1op,GE1no2GE2no2)

..

It is not easy to evaluate how the difference between the slurring of sources in bars 8-9 (and similarly in bars 24-25) occurred. A includes two slurs in both places, although for the first time, when bar 8 appears at the end of the text's line, one could consider the slur in bar 9 to be a continuation of the previous. One-bar slurs are also in AI (except for bar 9, devoid of a slur). In this situation, one has to assume that the slurs of FE (→EE,GE1op,GE1no2→#GE2op2), combined in both places, could have been a result of Chopin's intervention. However, without being sure in this respect, in the main text we give the slurring of A, confirmed by AI. The version of FE, with a phrasing combining structural divisions (cf., e.g., the Waltz in A No. 3, bars 40-41), characteristic for Chopin, particularly in later pieces, can be considered to be (perhaps) an authentic variant.

b. 8

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

..

In GC the 10th quaver in the L.H. is a g. The mistake was corrected in GE, probably on the basis of analogy to the previous, similarly constructed triplets in this bar and in bar 6.

b. 8-24

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

..

In bars 8 and 24 there are no accidentals in the part of the L.H. in the autographs. In bar 8 FE added – perhaps at Chopin's request – a cautionary  before d, which was repeated in all editions. In GE and EEW2 a similar addition was performed in bar 24.

b. 8-16

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

..

We add a cautionary  next to gin bar 8 and 16. One of them was written by Chopin himself in bar 8 in AI, while both signs were added by the revisers of GE and EEW1 (→EEW2).

b. 8

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

..

Same as bars 2, 5 and 12-13, in GC bar 8 is written in an abbreviated manner with / signs (one on each stave). The interpretation of this notation, undoubtedly repeated after [A], turned out to be not entirely clear – see bars 7-8.
