There are over 2.7 trillion known digits of Pi. This irrational (non-repeating) number we all remember from primary school has inspired all manner of artistic endeavors, from Kate Bush’s song “Pi” to Martin Krzywinski’s data artworks. Now, for Pi Day (March 14), music software programmer Canton Becker has crafted a million-hour song based on Pi that unfolds generatively on a virtual tape deck.
Titled “Shepard’s Pi,” the song combines two of Becker’s favorite infinities: Pi, and an auditory illusion called a Shepard tone, which he describes as an “unsettling sonic illusion of a pitch that climbs or descends forever, never reaching a top or a bottom.”
