[ about ]
Gesture Synth is a browser-based musical instrument that uses your camera to detect 1–5 finger gestures and convert them into tuned notes or chords. It runs entirely in your browser without requiring MIDI keyboards, plugins, installations, or accounts. The synth offers four different voices and allows you to record music clips locally.
The software processes live video and hand landmarks directly on your device for privacy and responsiveness. It includes guided songs to help beginners learn and play complete melodies with gesture-based controls, along with options for brightness and sound shaping through hand movements.
Gesture Synth is designed for ease of use, requiring no prior musical experience, and works best with current versions of Chrome, Edge, or Safari on camera-equipped devices.
