Harmonic Phasing A fundamental with 9 harmonics randomly moving in and out of phase. A few iterations. Made in p5.js

// p5
let h=[],f,l=[]
function setup() {f=random(99);for(i=1;i<=9;i++) {o=new p5.Oscillator();o.freq(f*i);o.amp(.3/(i*i));o.start();h.push(o);l.push({rate:random(.1),phase:random(TWO_PI)})}}
function draw(){t=10;h.forEach((o,i)=>o.freq(f*(i+1)+sin(t*l[i].rate+l[i].phase)*f*(i+1)*.2))}

That’s it. It’s meant to act quick peak to 0 for triggering external circuits. The next one will be more “musical”. There’s a whole record and writings on the idea here. tinyurl.com/mjnd3zkx

In an effort to use social media as a force for creative good and general well being, I am going to use this account to share sound/music/video works written in code that can be realized by running it as-is. All under the 300 character limit. I'll include my own realizations, when applicable.
