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

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.

c1 ×3 in As, 1st version, probable reading

In bar 8 the version of the R.H. adopted by us as the text of As (written in the main course of the text's line of As) is partially hypothetical, since the 1st quaver is blurred, whereas in the second the bottom note is unclear. One can consider the version of AI (excluding the rhythm) to be an alternative interpretation of this notation. The second of the given versions of As is written over the R.H. and under the L.H. of the first, probably with an intention to choose one of them later. In the version prepared for print, Chopin opted for an intermediate version in the R.H., in which dappears only in the 1st quaver, while in the L.H. he returned to the original version. The absence of  before din the alternative version of As is a patent inaccuracy – the sign is in the previous bar.

In bar 24 all sources feature the same versions as in bar 8.
