John Cage’s “Cello Etude Boreales, no. 1” (1978) performed by Drake Driscoll, Northwestern University’s Bienen School of Music, Class of 2018. The pieces was created using star charts from the Atlas Borealis as a source of randomness. Cage traced the star maps and then used additional chance operations to determine, with painstaking precision, the specific qualities of those events (pitch, dynamics, duration, timbre, articulation).
