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

In A the  to d4 in bar 319 is missing, while in bar 320 a  at this pitch is the only one written by Chopin. All the overlooked accidentals were added in GE (→FE,EE,IE).

Long accent in A, contextual interpretation

No marking in EE

..

The fact that the  mark visible in A is a long accent is confirmed by  used by Chopin in an analogous situation 4 bars earlier. The absence of the mark in EE is one of a few oversights by the engraver in this place – see the next notes.
