Issues : Inaccurate slurs in A

b. 15

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

Slur from a1 in A, GE2op (→GE3op) & GE2Ab.

Slur from g2 in FE (→EE)

No 2nd slur in GE1op & GE1Ab

..

The moment of the division of the slur – after the 3rd or the 4th quaver of the bar – is not completely clearly marked in A. The interpretation of FE (→EE) is graphically less likely and at the same time pianistically less natural, therefore, in the main text we choose the first, definitely more likely possibility. Such slurs are given in GE, yet in GE1op and GE1Ab there is no second slur (until bar 22), which is undoubtedly a mistake.

b. 16-22

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

Slurs in A, literal reading (→FEEE)

Slur in A (contextual interpretation), GE2op (→GE3op) & GE2Ab

No slurs in GE1op & GE1Ab

..

Due to the applied abbreviated notation of bars 17-31, it is not entirely certain how the slurs of A at the transition between bars 16 and 17 are to be interpreted. According to us, it is more likely that Chopin though about a continuous slur, which is indicated by the fact of combining slurs in A in analogous bars 124-125 (a respective change was introduced in later GE). Omission of the slur in GE1op and GE1Ab is a patent mistake.

b. 31

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

Slur from a1 in A, GE2op (→GE3op) & GE2Ab.

Slur from g2 in FE (→GE1op,GE1Ab,EE)

..

Same as in bar 15, the moment of the division of the slur in A is not entirely legible. In the main text we give the most natural, as far as the piano technique is concerned, division after the 3rd quaver in the bar.
