Online Piano Keyboard
A free two-octave piano that plays right in your browser. Click the keys, tap them on your phone, or play with your computer keyboard. Change the waveform, volume, octave and sustain to shape the sound.
Computer keys: A W S E D F T G Y H U J K play one octave (hold a key, press others to play chords).
How to use
- Press the keys with your mouse, touch, or the computer keyboard row A W S E D F T G Y H U J K.
- Try different waveforms: triangle sounds soft, sawtooth sounds edgy.
- Turn sustain on if you want notes to ring out after you release them.
- Use the octave buttons to move the keyboard between C3 and C6.
Note: Sound is generated live with the Web Audio API, so nothing is downloaded and no audio leaves your device. If you hear nothing, check that your device volume is up and your browser is allowed to play sound.
