Slur in FE0

Long slur in FE1

Four slurs in FEG (→GE1)

Four slurs in EE

Five slurs in GE2 (→GE3)

..

The slurring in bars 159-164 is clearly incomplete in FE0, which may be a result of Chopin's inaccuracies in [A], errors of the engraver or both. Chopin then changed and completed the slurs in FEG, the base text to EE and proofreading of FE1, yet in all of them differently. In total, it gives three different authentic slurring versions. In the main text we give the version written by Chopin's hand in FEG (→GE1), as in the case of FE and EE, there is a slight possibility that Chopin proofreading was overlaid with certain mistakes, manners or revisions of the engravers.
It is not entirely clear what the motivation of the reviser of GE2 (→GE3) was at the time of breaking the slur between bars 159 and 160.

b. 160

composition: Op. 42, Waltz in A♭ major

..

In FE0 (→FE,FEG) there are no naturals raising d1 to d1 on the 2nd crotchet in the L.H. and d2 to d2 in the R.H. It is undoubtedly Chopin's mistake  – cf.  in the next bar. The necessary signs were added in EE and GE, they were also added in pencil in FED (only before d1) and in FEJ (both).

b. 160

composition: Op. 42, Waltz in A♭ major

..

The natural before b1 in the chord on the 3rd beat of the bar is only in GE2 (→GE3). In this context the need to use this sign is an issue of convention.

b. 164-165

composition: Op. 42, Waltz in A♭ major

..

In FE0 (→FE,FEG) there is no change to the bass clef here. The sign was erroneously added in GE1, by placing it only after the 1st crotchet in bar 165. Eventually, the error was corrected in GE2 (→GE3). EE also features the clef in the correct place.
