Aci jazz (also known as club jazz) is a musical genre that combines elements of soul music, funk, disco, particularly looping beats and modal harmony.. It first developed in America in a simplistic form from artist such as Sonny Stitt who infused funk, gospel, jazz, and other popular genres with a recurring backbeat. In the UK it developed over the 1980s and 1990s and could be seen as tacking the sound of jazz-funk onto electronic dance/pop music for the UK.
