Brief

A website (shared by @om_patel5 on 2026-08-05) converts webcam-tracked hand gestures into playable electronic music. Left-hand positions select chord degrees and modify quality and timbre, while right-hand pinches add effects; a hand-controlled chop rate (1/4–1/32) and live BPM/swing keep everything in time. The system runs entirely in-browser with no data sent off-device.

Why it matters

Author @om_patel5 (published 2026-08-05 01:52:50+00:00) shared a website that uses your webcam to turn hand movements into electronic music with no controller, MIDI keyboard, or external hardware.

Key details

  • Left-hand gestures map to harmony: finger count selects chord degree (1 = i, 4 = iv), palm flip toggles major/minor, pointing fingers down flattens, wrist roll sweeps filter cutoff, and hand height adds 'spice' up to a 7th.
  • Right-hand pinches control FX (index = filter, middle = delay/reverb, ring = stutter gate, pinky = bit crush; fist clears); live chop rate adjustable by hand from 1/4 to 1/32, all synced to live BPM and swing, and the processing runs locally in the browser so nothing leaves your device.

SOMEONE BUILT A WEBSITE THAT TURNS YOUR HAND MOVEMENTS INTO ELECTRONIC MUSIC

no controller, midi keyboard, or hardware at all

you just move your hands in front of your webcam and it makes music

> your left hand is the chord instrument
> hold up fingers to count the chord degree, one finger is the i, four fingers is the iv, and it plays that chord in key
> flip your palm over to switch between major and minor, point your fingers down to flatten it, and roll your wrist to sweep the filter cutoff
> hand height controls how much spice is in the chord, so raising your hand takes a basic triad up to a 7th
> your right hand is the fx and dj side. pinch different fingers for different effects, index is the filter, middle is delay and reverb wash, ring is a stutter gate, pinky is bit crush, and a fist clears everything
> theres a live chop rate you control by hand too, 1/4 through 1/32
> everything is timed to a live bpm and swing, so it stays in time while you play

the whole thing runs on your webcam in a browser tab, nothing to install and nothing leaves your device
