Slurs

b. 139-140

composition: Op. 42, Waltz in A♭ major

..

In GE1 the slur was erroneously led up to the 3rd crotchet, from which the new slur starts simultaneously. A relevant correction was performed already in GE2 (→GE3).

b. 152-165

composition: Op. 42, Waltz in A♭ major

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. 210

composition: Op. 42, Waltz in A♭ major

..

In FE0 (→FE) there is no slur in the L.H. in bar 210. In the next bar, beginning in this source from the new line, the slur is continued, which, apart from purely musical arguments, additionally confirms the engraver's oversight. Chopin did not correct the mistake in FEG, yet in spite of this fact, the reviser of GE added the slur. EE also has the correct version.

b. 227

composition: Op. 42, Waltz in A♭ major

Quavers without slur in FEG & FE1

Quavers with slur in GE & EE

..

FE0 has a whole rest in the L.H. In FEG (→GE) Chopin added two quavers and relevant rests. He must have introduced a similar change also in the base texts to FE and EE. According to us, the quavers – same as the previous ones – were supposed to be embraced with a slur, in spite of the fact that it is absent in FE and in FEG (if we are to believe the photocopy of this source, which is not of the highest quality).

b. 230-231

composition: Op. 42, Waltz in A♭ major

..

In FE0 (→FE,EE) the slur ends on the last semiquaver in bar 230. In FEG (→GE) Chopin extended the slur to the 1st crotchet in bar 231. The composer probably overlooked the respective correction in the base texts to EE and FE.
