It's Got a Beat

Clapping Music is a minimalist piece written by Steve Reich in 1972. Where one performer claps a basic rhythm, a variation of the fundamental African bell pattern in 12/8 time, for the entirety of the piece. The other claps the same pattern, but after every 8 or 12 bars s/he shifts by one eighth note to the left. The two performers continue this until the second performer has shifted 12 eighth notes and is hence playing the pattern in unison with the first performer again (as at the beginning), some 144 bars later. The variation of the African bell pattern is minimal; it contains just one additional beat. With simple video editing, key "slap" scenes of Angie Dickenson hitting Lee Marvin re-creates the pattern. (More or less..). From the film 'Point Blank!'.
