A now nearly obsolete description of ornament, available only on keyed instruments, in which an essential note of a melody is struck at the same moment with the note immediately below it, the latter being instantly released, and the principal note sustained alone.
It is generally indicated by:
- a small note with an oblique stroke across the stem
- when used in chords by a line across the chord itself
Its use was latterly confined exclusively to the organ, where it is of some service in giving the effect of an accent, or sforzando, to either single notes or chords; but the practice in generally discredited in the present day.
The term Acciaccatura is now very generally applied to another closely allied form of ornament, the short appoggiatura.« Back to Dictionary Index
