Air Piano — Play with Your Hands

How to Play

1. Click Enable Sound first — browsers require a user tap to unlock audio. You'll hear a test note (middle C) and the button turns green.
2. Click the camera area to start — allow camera access when prompted. Sit ~50–80 cm from your camera in a well-lit room.
3. A two-octave piano keyboard will appear overlaid on your camera feed, with white and black keys visible across the upper portion of the view.
4. Hold both hands above the keyboard with fingers pointing downward, as if hovering over a real piano.
5. Tap a finger downward through the bottom edge of any key to strike it. The key glows and plays the note.
6. Play chords by tapping multiple fingers at the same time — both hands are tracked independently.
7. Black keys are the narrower dark keys between the white ones — tap them precisely in the upper portion of the keyboard.

How It Works

The piano has been called the "king of instruments" for its incredible range and versatility. With 88 keys spanning over seven octaves, it can produce everything from thunderous bass to sparkling high notes. This Air Piano gives you two full octaves (C4 to C6) — the middle range where most melodies and chords live. The white keys play the natural notes (A, B, C, D, E, F, G), while the black keys provide the sharps and flats that add color and emotion to music. A standard piano produces sound when felt hammers strike tuned steel strings inside a wooden soundboard, creating rich overtones and sustain. You can play single-note melodies, simple two-note intervals, or full chords with all five fingers. The reverb option simulates how sound bounces around a concert hall, adding depth and warmth to each note you play. Whether you are learning your first scale or playing a favorite tune, the piano layout makes music theory visible and intuitive.
