d2 in A & GE1op

..

The absence of a  before the 4th quaver in bar 144 is probably Chopin's mistake (cf. bar 143). The sign is present in As and it was added in the proofreading of FE (→GE,EE; in GE1op it was misplaced in bar 143).

b. 160-164

composition: Op. 64 No 3, Waltz in A♭ major

Four-note chords in A & GE

Three-note chords in FE (→EE)

..

The version of A, repeated in GE through a proof copy of FE, is the original one. In this version in each bar one is supposed to perform two identical four-note chords (as in the previous bars). In the last proofreading of FE (→EE) Chopin deleted some of the notes, lightening the accompaniment and creating an internal melodic line: g–d1c1a etc.

 up to bar 168 in A

A longer  hairpin may be a result of Chopin's proofreading. However, taking into account a possibility of a mistake of the engraver, in the main text we give the undoubtedly authentic, simpler notation of A.
