b. 196

composition: Op. 42, Waltz in A♭ major

c2 in FE0 (→FE,EE,FEGGE)

a1 in GE2 (→GE3)

..

At the beginning of the bar FE (→FEGGE1,EE) has a c2, which is most probably a characteristic error of the engraver (the so-called Terzverschreibung). In analogous bar 24 in all sources there is an anote. A respective correction was introduced in GE2 (→GE3).

b. 203

composition: Op. 42, Waltz in A♭ major

E suggested by the editors

e in FE, GE & EE

..

In analogous bar 31 Chopin changed e to E, both in FEG (→GE) and in the base text to EE. The fact of leaving e unchanged in bar 203 may be a result of Chopin's oversight of a relevant correction, therefore, in the main text we give E also in this bar.

b. 217

composition: Op. 42, Waltz in A♭ major

..

In the entire bar FE0 (→FE,FEG) has only two cautionary accidentals: a  lowering g2 to g2 on the 3rd quaver and a  raising a1 to a1 in the L.H. Out of three undoubtedly overlooked signs in the R.H., it is the lack of the  raising a1 to a1 at the beginning of the bar that is most striking; the accidental was added in pencil in FED, it was also added in GE and EE. In both editions a  was added also before the last quaver, yet the fully correct notation is only in GE.

b. 218-219

composition: Op. 42, Waltz in A♭ major

..

In both bars in FE0 (→FE,FEG) there is not any  lowering g3(2) to g3(2). The flats in bars 217 and 220 prove Chopin's oversights, probably still in [A]. Some of the necessary signs were added in pencil by the composer in FED (both before g3) and in FEJ (at the beginning of bar 219). They were also added in GE and EE (the sign in bar 218 only in GE2 and GE3).

The cautionary  next to eis only in GE2 (→GE3).
