Italian electronic maestro Pietro Grossi composed Battimenti in 1965, using 94 near frequencies sectioned into groups of 2, 3, 4, or 5. The overlapping and interfering frequencies create a shimmering bed of sound, rich with harmonic beatings and deep overtones. The piece progresses additively, beginning with a study for two simultaneous sounds and growing from there. Originally considered just the building blocks for a latter piece, Battimenti stands on its own as a profound forerunner to later minimalist activities.
