Sound

This was the sketch Julia Qi and I made. We started together exploring what we learned in class implamenting the drums. I wanted something which pitched up over time and kind of ascended up into space. Trying to figure this out, I wrote the concatinated drum line. I planned to revsit it, but was so busy in this part of the semester that I let it be. Julia wrote the melody.

I used claude to generate the start and stop button. The code before I did so is written below:

let drum
let factor = 1
let minInterval = 10
let maxInterval = 60
let interval = maxInterval
let beat = 60
let melodyNotes = [
  300,200,800,700,500,400,200,100, 
  500,400,800,700,500,400,100,200,
  300,200,800,700,500,400,200,100, 
  500,400,800,700,500,400,100,200,
  300,200,800,700,500,400,200,100, 
  500,400,800,700,500,400,100,200,
  300,200,800,700,500,400,200,100, 
  500,400,800,700,500,400,100,200,
]
let melodyRhythm = [1, 1, 1, 1, 1, 1, 1,1,
                  1, 1, 1, 1, 1, 1, 1, 1,
                   0.5,0.5,0.5,0.5,0.5,0.5,0.5,0.5,

                   1,0.25,1,0.25,1,0.25,1,0.25];

  noStroke();
   melodyOsc = new p5.Oscillator('triangle');
  melodyOsc.amp(0.12);
  melodyOsc.start(); 
  melodyOsc.freq(melodyNotes[0]); 
  noiseSeed(1);
}
function draw() {

  if (frameCount%beat == 1) {
      playSound(.1);
      console.log(1);

    let baseFreq = fromFreq + (toFreq - fromFreq) * (1 - cos(progress * PI)) / 2;
