Frequently Asked Questions
Do I need to install anything to play?
No. The piano runs entirely in your browser using the Web Audio API. No plugins, no apps, and no sign-in are required. Just open the page and click a key.
How do I play with my computer keyboard?
The lower letter row (Z X C V B N M) plays Octave 3 white keys, with S D G H J for the black keys. The top row (Q W E R T Y U) plays Octave 4 white keys, with 2 3 5 6 7 for the black keys. I O P cover Octave 5 white keys (9 0 for sharps). Hold multiple keys simultaneously for chords.
Can I play chords?
Yes. The piano is fully polyphonic. You can press multiple mouse buttons, touch multiple keys on a touch screen, or hold several keyboard keys at the same time to play chords.
Does it work on mobile and tablet?
Yes. The keyboard responds to touch events on any touch-screen device. Scroll horizontally to reach all three octaves on smaller screens.
What do the Sound options do?
The Sound selector changes the oscillator waveform. Triangle gives a warm, mellow tone closest to an acoustic piano. Sine produces a pure, smooth tone. Square has a hollow, organ-like character. Sawtooth is bright and buzzy, similar to a synth lead.
Why is there no sound when I first open the page?
Modern browsers block audio before the user interacts with the page. Click any key or press a keyboard key once and audio will activate for the rest of your session.
