Downtempo is the name used to describe chilled-out beats on a slower, groovier tip. Under this broad genre heading, chunky rhythms based on hip hop beats rule supreme. Downtempo is usually instrumental-based music in the hip hop vein, but can also draw from jazz, film scores, dub and reggae, and world music. Its overall form depends on bass and funk. Like house and drum and bass musicians, downtempo artists create morphed soundscapes that draw from a long history of musical genres. Downtempo is constantly reinventing itself, spawning new and unique variations like the "British sound," "French trip hop," and the hip hop-heavy U.S. approach.
