FC (→GE)

FE (→EE)

This is the most significant difference between the authentic sources – FC and FE – in entire opus 30. The FE (→EE) version, which is a clear improvement of the Mazurka ending, must have been introduced by Chopin in the proofreading of or in the basis for FE instead of the FC (→GE) version.

b. 65

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

d in As & AI

D in A (→FEGE,EE)

..

We assume that out of two notes written in As at the beginning of bar 65, d is intended for this bar, whereas D – for bar 81, which, like the entire second half of this section, is not explicitly written in the draft. AI features d in both bars, whereas the version intended for print – D in both bars.
The discussed d looks actually like a in As; such inaccuracies were very frequent in Chopin's drafts. Due to this reason, in order not to divert attention from genuine textual differences, we do not reproduce this notation even in the version transcription, since the correct pitch of the note is undisputed. Analogously in similar situations.
