A Webcam Music Instrument for Chords, Melody, and Beats

Turn a webcam into a free browser music instrument. Play chords, melodies, beats, and synth with expressive two-handed tracking.

Hand Jam turns a standard webcam into a playable browser instrument. One hand holds deliberate chord shapes while the other raises or lowers a scale-aware lead.

What this tool includes

No extra hardware

Start with a webcam, browser, speakers, and a clear view of your hand. There is no plugin or MIDI controller to install.

Two-handed play

Use one hand for chord shapes and the other for a scale-aware lead. Chords mode adds tone, filter, and beat controls.

Local by design

Camera processing stays in the browser during play. Recording begins only when you explicitly open Cover Studio and press Record.

Phone-ready framing

Prop the phone at hand height, use even light, and leave enough space for both hands to stay visible.

Performance tools

Add a beat, arpeggiator, polyrhythm, count-in, microphone, overlays, and reviewable local video.

How to use this tool

  1. Open the instrument: Launch Hand Jam from a current browser over HTTPS.
  2. Start the instrument: Press Start camera and allow access when the browser asks.
  3. Frame your hand: Use even light and keep the playing hand fully visible to the camera.
  4. Play and shape: Use hand shapes for chords, a pointing finger for melody, and the second hand for tone.
  5. Record only when ready: Open Cover Studio to make a local take with optional microphone and backing track.

Practice tips

  • Place the camera at hand height and leave enough space around the fingers for the full outline to remain visible.
  • Use a plain, evenly lit background when the hand landmarks are difficult to read.
  • Start in Chords mode before adding Air Melody, filter movement, or Air Dock actions.
  • On mobile, rotate the device when the camera stage needs more width for both hands.

Webcam instrument questions

Does the webcam video leave my device?

Hand tracking runs locally in the browser. Play mode does not record a take; Cover Studio only captures a local performance after you choose Record.

What do I need to use the webcam instrument?

Use an HTTPS browser with camera permission, Web Audio support, and enough light for the hand landmarks to stay visible.

Can I use it on a phone?

Yes, when the browser supports camera access. Prop the phone at hand height and keep the full hand in even light.

Do I need a webcam?

Yes. MOTION is designed around live camera hand tracking; video is processed on your device and is uploaded only if you publish a take.
