30 chromatic metronomes at 0-29 BPM (2011)

30 Metronomes, set from 0bpm to 29bpm, each triggering a note from the chromatic scale starting at C# and increasing sequentially. Branching off a project I’ve been developing for a few years with Mira Calix inspired by Ligeti’s Le Poeme Symphonique for 100 metronomes.

This particular incarnation is also inspired by http://www.memo.tv/simple_harmonic_motion

The period duration of the pattern is exactly 1 minute.

I was aiming to keep the full code less than 126 characters (so I could tweet it with the #supercollider hashtag):

Technically this isn’t phasing as made famous by Steve Reich. His phasing works were built on the concept of playing the same pattern simultaneously, altering the tempo for each instance. “30 Chromatic metronomes” could be forced under the ‘phasing’ umbrella if it is considered as phasing an extremely simple pattern (i.e. a single ‘hit’) with 30 instances but adding a pitch shift. It can also be thought of as a 30-part polyrhythm.
