b. 221

composition: Op. 42, Waltz in A♭ major

..

In FE0 (→FE,FEG) two  lowering  c3 and c4 to c are missing. The necessary signs were added in GE1 (→GE2GE3). EE has only the first

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).

composition: Op. 42, Waltz in A♭ major

No e1 in chord in FE0 (→FE,EE,FEGGE1)

e1 in chord in GE2 (→GE3)

..

GE2 (→GE3) added an arbitrary eto the chord on the 3rd crotchet. On the other hand, it cannot be entirely excluded that lack of this note is an oversight of the engraver of FE0, unnoticed by Chopin.

Slur in FE & EE

 
..

The slur over the R.H. was most probably added by Chopin in the base texts to FE and EE.

b. 237

composition: Op. 42, Waltz in A♭ major

..

There are no accidentals before the 2nd chord of the bar in FE0 (→FEG). This patent inaccuracy was corrected in FE1 (partially, as only a  before bwas added) and in GE1 and EE (both necessary naturals). In GE2 (→GE3) the third  before ewas added.
