b. 297

composition: (Op. 4), Sonata in C minor, Mvt IV

Short accent in A (→GEEE,IE)

No mark in FE

Long accent suggested by the editors

..

In A the accent is shorter than the similar marks in analogous bar 293, 305 and even 309. However, if we take into account the similarity of the rhythmic and harmonic context, this comparison proves that it is also in the discussed bar that Chopin almost certainly meant a long accent.
The missing mark in FE is most probably due to the engraver's oversight.

b. 298

composition: Op. 21, Concerto in F minor, Mvt I

..

There is an erroneous  before the 1st semiquaver in the L.H. in the 2nd half of the bar in FE1. The mistake was corrected already in FE2. It is probably a revision, although Chopin's participation cannot be excluded.

Wedge in A

Dot in GE1 (→FE)

Dots in EE & GE2

..

Reproducing the wedge over das a dot must be an inaccuracy of GE (→FEEE). In turn, the dot for the L.H., added in EE and GE2, is a revision of the editors.
