I've been working on a piece that uses the Harmonic Frequencies of two Pulsars as the basis for the tone sequences. Much like using traditional scales to develope harmonies and melodies, I used these numeric sequences to generate a sries of tones that I used as the melodic and harmonic reference. They are loosely based on the phase shift of a pulsating star as observed from earth based telescopes.
For those that are into this type of writing, I post the work here.
It is a unique ensemble to write for. I am looking locally to get a live performance of this work.
