Appoggiatura
The passing notes, neighbouring notes and anticipations described so far, all occur in metrically weak parts
of the bar. The appoggiatura is a dissonance which occurs on a strong beat. Like the suspension, it usually
resolves down by step, but it can resolve up a semi-tone.
An appoggiatura can be leapt to. In this case it can only be described as an appoggiatura.
It is possible, common in fact, to approach and leave an accented dissonance by step. In this case the
dissonance is called an appoggiatura by some, and an "accented passing note" by others.
If a suspended note is not actually tied over, but is repeated, it may be called an appoggiatura or a
suspension.
In the Classical repertoire, the cadencial six-four is, in a sense, a double appoggiatura. It is common to find
a triple appoggiatura on the final tonic.
