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. 217

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

..

In GC (→GE1) the bar includes only 5 crotchets, as the copyist overlooked the third chord. The mistake was corrected in GE2.

d1 in GC (→GE), FE3 (→FE4) & EE

No d1 in FE1 (→FE2)

..

No d1 notes in the 3rd and 4th chords in the R.H. is certainly a mistake of the engraver of FE1 (→FE2), corrected by Chopin in FE3 (→FE4) and the base text to EE.

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

in GC (→GE)

No indication in FE (→EE)

..

The absence of cresc. in FE (→EE) is most probably a result of the engraver's inaccuracy.
