b. 21

composition: Op. 28 No. 17, Prelude in A♭ major

Accent above a1 in A

No mark in FC (→GE) & EE

Accent under b in FE

..

The missing accent in FC (→GE) and EE are oversights of Fontana and of the engraver of EE. The mark having been moved to the side of noteheads in FE, i.e. in this case under the stave, is a frequent, routine revision; thus, the notation was left without a suggestion – certainly intended by Chopin – to accent the a1 note.
