Tap to play.

An offline piano across two octaves. Click the keys, use your physical keyboard, or trigger one of the songs below. The bottom row Z–M plays C4–B4, the top row Q–U plays C5–B5.

Twenty-four keys.

Web Audio API, no samples — pure additive synthesis with a piano-shaped envelope. Volume and sustain live in the toolbar.

Six classics, one tap.

Tap any title to auto-play. The piano lights up note by note. Tap again, press space, or hit any key to stop.

Where every note lives.

Two QWERTY rows, one per octave. Black keys sit above their white-key neighbours, exactly like a real piano.
