Online Piano: Play Grand Piano with Hand Gestures
Experience playing a concert Grand Piano and vintage Rhodes electric piano right through your webcam. Form hand shapes in thin air to trigger rich acoustic chords, inversions, and bass octaves with authentic studio-grade samples.
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:
Select Scale Degree & Chords
Raise 1 to 5 fingers on your left hand to play diatonic piano chords: 1 finger plays the Tonic (I chord), 2 plays Supertonic (ii chord), 3 plays Mediant (iii), 4 plays Subdominant (IV), and 5 plays Dominant (V).
Inversions, 7ths & Octaves
Use your right hand to dictate the piano chord inversion and color: 1 finger plays root position, 2 fingers plays 1st inversion, and 3 fingers adds a lush 7th note.
Sustain & Dynamic Expression
Notes continue sustaining seamlessly while hand shapes are maintained. Toggle the virtual sustain pedal in the dock to let chords ring freely.
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.
