About Pendulum Waves

I was essentially looking at this youtube video where you see a series of pendulums that are all slightly different lengths, and they form some cool patterns visually. I figured, we can connect some sound to that. And then kinda moved onward from there.

Again, the audio is very fun matching the physics simulation, but I wanted to be able to tune/tool it, so added options to change the notes, and the lengths of said notes. That said, as has happend before, I’m not much of a musician so I couldnt wrangle anything particlarly cool out of the toy. If someone does, send it to me, urls should be save-able and controls like left/right keys will help you compose quickly.

The Hows

  • Each pendulum has a slightly different length, giving it a different swing period
  • The pendulums are tuned so they complete different numbers of swings in the same cycle
  • When a pendulum crosses center, it triggers a musical note
  • The collective pattern evolves from synchronized to scattered and back

Buttons and Knobs

  • Pendulum count: Adjust how many pendulums swing (3-24)
  • Cycle time: How long until all pendulums realign
  • Scale: Choose the musical scale for the notes
  • Sound: Pick the synth sound
  • Damping: How quickly pendulums lose energy
