Atlas Eclipticalis/Winter Music – Atlas Eclipticalis (for up to 86 instruments), performed here by a chamber ensemble of flute, bassoon, trumpet, trombone, harp, violin, and violoncello, is coupled with Winter Music (for 1 to 20 pianos), performed here by two pianos. Electronics are also engaged using random processes similar to Cage’s Cartridge Music. Page 3 of the four-page Atlas Eclipticalis score was used for all parts, giving a performance length of 20 minutes and 45 seconds. Each page has five systems (lines). Space horizontally equals time. Each system took 4 minutes and 10 seconds to complete in this performance.
