Pendulum music is a moving sound installation consisting of a series of parallelepipeds (cardboard boxes originally containing mechanical pianola rollers), stretched and attached to the wall at equal distances. In their suggestive seriality they are reminiscent of anomalous pendulum clocks: the brass rods attached to the underside of each box, in fact, move perpendicularly to the wall, rather than in parallel, as is usual. The lower end of each rod terminates with a metal clock mechanism, each one different from the other, and it is these, through the random wave-like movement of the pendulums, that rhythmically touch the wall, producing a delicate sound. Each of the work's constituent elements leads back to music (the mechanical pianola evoked by the parallelepipeds) and to the very idea of time (the pendulum, the clock mechanisms), while the oscillatory process marks an ancestral rhythm.
