b. 13-14

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

..

The sharps raising d3(2) to d3(2), overlooked in the manuscripts, were added in FE (→GE,EE). It is a typical inaccuracy of the Chopin notation.

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. 17-24

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

..

In As (→A) bars 17-31 are not written out, but only marked as a repetition of bars 1-15 (in As the only signal of the anticipated repetition are two versions of the ending, corresponding to bars 16 and 32).

b. 17-19

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

 in bars 17-19 in A (→FEEE) & GE2Ab

No sign in GE1op & GE1Ab

 in bar 18 in GE2op (→GE3op)

..

GE1Ab and GE1op overlooked the  sign. In GE2op (→GE3op) the hairpin was added, but only in bar 18, which is an arbitrary revision.
