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. 218-219

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

..

GC includes identical sets of accidentals in the last chord in the R.H. in bar 218 and the first one in bar 219 – a  before the top bottom note (d2) and a  raising g2 to g2. In GE1, the  in bar 218 was printed before e2, which has to be considered to be a mistake, as the sign before dwas placed correctly, whereas the  before eshould have been already in the previous chord. In GE2 it was noticed that in bar 219 the  is supposed to concern the adjacent note, e2, however, the erroneous notation of bar 218 was left unchanged. FE (→EE) include the correct notation.

It is worth observing that in GC and FE the  before gin the last chord in bar 218 is not unnecessary, as the sign is absent in the previous crotchet.

In the main text, we add a cautionary  before din bar 218.

No bottom g1 is certainly an oversight of the engraver of FE (→EE).

We give the  indication exactly after A. It indicates, together with the slur embracing the octave leap, that the variant of the initial motif of this movement of the Concerto should be played distinctly. The detail was inaccurately reproduced in the editions. Similarly in bar 220.
