Abstract

A hand-operated musical rhythm pattern generator includes two independently rotatable discs mounted in a holder. The discs have complementary rhythm patterns printed on the peripheries thereof, a portion of which is visible through a window in the holder. The rhythm patterns displayed may be randomly changed by rotating one or both discs any desired angular amount.
