Appoggiatura

Chambers's Encyclopaedia, Volume 1: A to Beaufort, p. 349–350

Appoggiatura ('leaning note'), an Italian musical term, designating a form of embellishment by insertion of notes of passage in a melody. The appoggiatura notes are printed in a smaller character than the leading notes of the melody, and should always be given with considerable expression. There are two species, the long and the short. The former is now seldom printed, the music being written as played; the latter is usually termed an Acciaccatura, and written with a short stroke across the stem of the note. The appoggiatura proper takes half its length from the note it precedes, except when preceding a dotted note, from which it takes a third. The following is an example:
