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).

Our suggestion

..

Chopin added the  hairpins in FEG, yet in GE1 (→GE2GE3) they are absent. The sign is also absent in FE and EE.

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.

b. 231

composition: Op. 42, Waltz in A♭ major

e-a-d1 in FE0 (→FE1,FEGGE1)

e-b-d1 in EE & GE2 (→GE3)

..

On the 2nd crotchet FE0 (→FE,FEGGE1) has an undoubtedly erroneous e-a-dchord. Its correct sound, with the middle component being a b instead of a, may be established by comparing it with analogous bar 247. This version is included in EE, perhaps on the basis of Chopin proofreading of the base text, as well as in GE2 (→GE3).
