b. 161-165

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

3 slurs in A (→FEGE1op,GE1Ab)

4 slurs in EEC

3 slurs in EEW1 (→EEW2)

1 slur in GE2op (→GE3op) & GE2Ab

..

In the main text, we give the undoubtedly authentic slurring of A (→FEGE1op,GE1Ab). The same slurring was inaccurately reproduced in EEC. In turn, two remaining versions bear traces of intentional changes, arbitrary, although, from the practical point of view, quite accurate (particularly EEW).

b. 169-170

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

 up to bar 168 in A

 up to bar 170 in FE (→GE,EE)

..

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.
