An orrery is a mechanical, clockwork model of the solar system that demonstrates the relative, sometimes complex, and seemingly autonomous motions of the sun, planets and moons. Several sounds in this work are mechanically programmed to respond to the sonic behavior of each other. The ecology of their interaction defines their behavior and sonic transformation, generating a unique universe of sound at the moment of creation (performance). I completed this work on June solstice, and so the title for this particular sonic orrery seemed inescapable.
