Issues : Omission of current key accidentals

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. 218

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

The notation of accidentals in the penultimate chord in the R.H. in bar 218 is inaccurate in the sources. The  raising e2 to e2 is absent in all sources, whereas the  raising g2 to g2 is present only in GE and EE.

b. 219

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

The  raising c2 to c2 at the end of bar appears only in FESch (written in), FE4 and EE2. The absence of this accidental constitutes an undoubted oversight by Chopin in [A] – cf. e2 and not e2 in an analogous passage in bars 91-92.

b. 220-221

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

In [A], there was neither  raising g3 to g3 in the last crotchet of bar 220 nor  raising e3 to e3 at the beginning of bar 221. These obvious inaccuracies were only corrected in some sources –  was added in FE4, GE and EE2, and  in FE2 (→EE,FE3FE4).
