How Was Pi Used To Make This Music?

A music generating algorithm was composed to produce music using the first one billion digits of pi (π). These digits supply the "turn signals" used to determine every musical expression in the album. Each digit (3.1415...) is responsible for orchestrating approximately four seconds of music. The electronic instruments and sound samples were prepared by the composer in advance.

Because the numbers in pi never repeat, each of the million hours of "Shepard's Pi" music are in fact unique. By fast forwarding to some distant moment in the song, you are virtually guaranteed to find yourself listening to something that nobody else – including the composer himself – has ever heard before.
