In music, vamping is the repeated use of a phrase through an entire song or the improvisation on top of a repeated phrase through a song. Looping, samples and grooves are all examples of vamping, as is almost all popular music with repeated chord progressions.

A vamp is an attractive, dangerously flirtatious woman. A vamp in an old movie might wear tight clothes and bright red lipstick.
