vamp (music)

In jazz, gospel, soul, and musical theater, a vamp is a repeating musical figure or accompaniment. A vamp typically outlines a single harmony, or in some cases a familiar sequence of chords, such as ii-V(7) or IV-V(7) (in the key of C, this would be d minor and G 7 or F to G). The equivalent in classical music is an ostinato.
