How do I play the piano with my computer keyboard?

Keep the "Show computer keys" box ticked and the letters appear on the piano keys. The lower row Z S X D C V G B H N J M plays one octave from middle C, and the row above it, Q 2 W 3 E R 5 T 6 Y 7 U, plays the next octave up. The keys , L . ; / and I 9 O 0 P continue upward. Letters are placed by key position, so other keyboard layouts work too.

Can I play chords on a phone or tablet?

Yes. The keys respond to several fingers at once, and you can slide a finger across the keys. The piano shows 2 octaves on a narrow phone, 3 on a tablet or small laptop and 4 on a wide screen. Use the "+" and "−" buttons beside "Octave range" to move to higher or lower notes.

What do Sustain and Reverb do?

Sustain works like a piano pedal: while it is down, notes keep ringing after you let go of the keys. Hold Space on a keyboard, or press the "Sustain" button to keep it down. "Reverb" adds the sound of a room, from 0 to 100 percent.

How do I record and save what I play?

Press "Record", play, then press "Stop recording". Use "Play recording" to hear it, then choose WAV or MP3 and press "Download WAV" or "Download MP3". A recording can be up to 5 minutes long. WAV is saved straight away. MP3 downloads a one-time encoder of about 30 MB the first time you use it.

Is this a real piano sound?

It is a synthesised piano-like tone made in your browser with WebAudio, using no recorded samples. Each note blends several harmonics with a hammer-like start and a decay that is shorter for high notes. It is good for practice, tunes and sketches, but it is not a replacement for a sampled concert piano.

Yes. Every tool is free to use, with no account and no credit card. The work runs on your device rather than on our servers, which is what keeps it free to run.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install.

How It Works

The page builds each piano note in your browser with WebAudio oscillators and filters, so no sound files are downloaded, and renders recordings on your device.
