Tripolar Expedition

This algorithmic piece picks random notes from the Bohlen-Pierce scale for a soothing ambient effect. There are 17 iterations, each dropping the highest note from the list. It was composed in Java using the JMusic library.

Bountiful Providence

Overlapping Bohlen Pierce chords. Each note includes a harmony 439 cents (9/7) above and another 439 cents below. A pleasant effect with no real parallel in the 12-tone system.

“Providence”

A longer version of the algorithm sheds high notes as it progresses:

“Bountiful Pulsar”

Ambient Electronics

This was sourced from an old Bohlen Pierce programming experiment, remixed in Audacity. It’s called Below Presence 30.
