A film score (also sometimes called background score, background music, movie soundtrack, film music or incidental music) is original music written specifically to accompany a film.
In music, a cadenza (from Italian: cadenza, meaning cadence; plural, cadenze) is, generically, an improvised or written-out ornamental passage played or sung by a soloist or soloists, usually in a "free" rhythmic style, and often allowing for virtuosic display.
During this time the accompaniment will rest, or sustain a note or chord.
Thus an improvised cadenza is indicated in written notation by a fermata in all parts.
A cadenza usually will occur over the final or penultimate note in a piece, or over the final or penultimate note in an important subsection of a piece. It can also be found before a final coda or ritornello.
"Cadenzando" is a musical project of Richard Dobeson
