b. 193

composition: Op. 42, Waltz in A♭ major

..

In FE0 there is no  next to d. The mistake was overlooked by Chopin in FEG (→GE1). The missing sign was already added in GE2 (→GE3) and FE1 and EE.

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).

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.
