definition vamping
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. It is not a negative attribute, but implies building on top of a groove to create a song. The keyboardist used extensive vamping to create an intricate song based on a funk groove.
