Online Music Maker: Build a Track with Your Hands
Tunevate is a browser music maker with no download and no sign-up. Play chords and basslines with hand shapes, tap out drum patterns with finger combinations, and stack everything into synced multitrack loops — a whole song built in the air, in one tab.
How Hand Gesture Tracking Works
Tunevate uses your device’s webcam and client-side computer vision to track 21 hand landmarks in 3D space with sub-millisecond precision. Here is how your hands shape chords, melodies, and sound parameters:
Lay Down the Chords
Pick a key, then raise 1–5 fingers on your left hand to play scale degrees I through V. Tilt your wrist to flip a chord between major and minor. The theory engine keeps every gesture in key, so the progression always fits together.
Add Beats and Texture
Switch on Drum Mode and the right hand plays a 31-slot kit by finger combination — kick, snare, hats, claps. Switch it off and the right hand shapes voicings, sweeps the filter with a wrist tilt, and rides volume with hand height.
Record and Layer
Arm the looper, wait for the count-in, and perform a pass — it snaps to the bar automatically. Layer the next part over it against the same clock. Keep stacking until the arrangement is done, then export a WAV mix or a reloadable project file.
Built for Real-Time Music Creation
Engineered with Tone.js, Web Audio API, and MediaPipe AI for professional synthesis, responsive acoustic instruments, and seamless loop recording.
Full Multitrack Arrangement
A layers mixer and an arrangement canvas: mute, solo, rename, re-gain and reorder every track, and see the whole piece on a pan-and-zoom timeline.
Real Instruments, Not Just Beeps
Sampled Grand and Rhodes piano, acoustic and electric guitar, bass, plus synth pad and lead voices — swap the voice on any track without stopping.
Gesture Drum Machine
31 drum slots addressed by 5-bit finger combinations, each a 16-step pattern locked to the master transport clock.
Export and Reopen
Render the mix to a 16-bit WAV, or save the entire project — tracks, drum kit, chart and settings — to a .tvate file and pick up editing later.
Nothing to Install
No DAW, no plugins, no drivers, no MIDI hardware. Open the page, allow the camera, and the music maker is running.
Private by Design
Hand tracking runs entirely in your browser with MediaPipe. Camera frames are never recorded, uploaded, or sent to a server.

Frequently Asked Questions
Everything you need to know about playing this instrument online with hand gestures.
Is this online music maker really free?
Yes — completely free, with no account, no trial, and no track or export limits. The only thing that ever leaves your device is anonymous usage telemetry, described in full on the privacy page.
Can I make a full song, not just a loop?
Yes. Tunevate has a full rhythm section, polyphonic harmony instruments, and a multitrack looper that locks every layer to a shared clock. You arrange parts on a canvas, mix them in the layers strip, and export the finished piece as a WAV.
Do I need a webcam or any music gear?
For the gesture studio you need a webcam (a laptop or phone front camera is fine) and nothing else — no MIDI keyboard, audio interface, or software. If you'd rather not use a camera, the No-Camera Studio plays the same engine by clicking.
Can I export my music to use elsewhere?
You can export a stereo WAV mix of the whole session, and save the project as a .tvate file to reopen and keep editing. MIDI and stem export are not supported yet.
Do I need to know music theory?
No. The built-in theory engine constrains every gesture to the notes of your chosen key, so the chords you play always work together — you focus on the arrangement, not on avoiding wrong notes.
