A webcam runs through MediaPipe to track hand movements. Each pointer fingertip controls one of two on-screen wheels. The left wheel selects the root note, and the right wheel selects the chord type. FluidSynth then plays the chord those two produce. You can play more than a hundred chord progressions and create as many sounds through a built-in synthesizer.
