b. 41

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

a-g1 in FE (→EEC,EEW1)

a-c1-g1 in AI, AII, AIII, GE & EEW2

..

On the 2nd and 3rd crotchet AI, AII, AIII, A, GE include a–c1–gchords. Chopin deleted c1 in the last proofreading of FE (→EEC,EEW1). The notes were returned in EEW2, most probably after comparison to GE.

b. 48

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

d1 in AI, AII, AIII, A (→FEGE,EEC) & EEW2

d1 in EEW1

..

Both addition of a  raising d1 to d1 in EEW1 and its deletion in EEW2 are arbitrary revisions of the publishing house. The first results from the conventional sense of harmony of the reviser performing a routine check of the notation of accidentals, whereas the second one – from comparison to FE or GE.

b. 50

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

..

The naturals raising g to g in the chord in the L.H. and g2 to g2 in the R.H. are not carefully written in the autographs – the sign in the L.H. is not present in any of them, while the sign in the R.H. is included only in AII and AIII. The signs were added in the proofreading of FE (→GE,EE), probably by Chopin.
