Gesture Synth is a free, browser-based musical instrument that uses webcam hand tracking to let you play music with natural hand movements. Control chords, harmony, volume, tone, and octave with two hands—no microphone or video upload required, and all processing happens locally in your browser.
Key benefits include:
- Two-Hand Control: Left hand selects chords (1-5 fingers, wrist tilt for major/minor), right hand shapes harmony, volume, filter, and octave.
- Two Modes: Gesture mode for chord progressions and Theremin mode for continuous pitch control.
- Private Local Processing: Camera frames processed in your browser, with no data stored or uploaded to servers.
- Loop Sequencer: Build performances with a four-track sequencer, export as WAV/MP3, and quantize timing for smooth playback.
- Learn Mode: Guided practice with public-domain songs like Twinkle Twinkle Little Star for skill development.
- Free & No Setup: No subscriptions, accounts, or payments—start playing immediately with a webcam.
Perfect for music enthusiasts, beginners, and content creators seeking hands-on, browser-based music creation without installation or technical barriers.
