b. 136-152

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

..

A cautionary  before d in bars 136 and 152 is absent in A – the signs were added, perhaps at Chopin's request, in the proofreading of FE (→GE,EE).

b. 159-160

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

No g1 in A & GE

g1 in FE (→EE)

..

The gcrotchet, struck in bar 159 and sustained as a minim in bar 160, was added by Chopin in the last proofreading of FE (→EE). This kind of diversification of subsequent appearances of repeating musical ideas belonged to Chopin's favourite composer tricks.
The proofreading also embraced a change of the graphic layout of the text – the 3rd quaver in the R.H. was moved to the upper stave.
