No download, no account.

More than a virtual piano

Plug in a MIDI keyboard

Connect a USB MIDI keyboard straight in your browser (Chrome/Edge), with sustain pedal and velocity: rare among online pianos.

Play with your computer keys

A DAW-style layout mapped by physical key position: works on AZERTY, QWERTY and QWERTZ with no setup.

Live chord naming + drone

Hold notes and the chord is named instantly; a built-in drone sustains a pedal note under your playing.

Metronome and 142 sounds

Tap tempo, 2/4 to 6/8 and three click sounds, plus 142 instrument sounds in 17 families: 120 General MIDI, 16 character presets and 6 acid instruments, 19 of them free.

Keyboard FAQ

Is the online piano free?

Yes, it is a free virtual piano: no sign-up, no download, no ads. It plays right in your browser.

Can I play chords?

Yes. Chord mode plays a complete chord from a single key, which makes it ideal to learn and practise chord progressions.

Can I use my computer keyboard?

Yes: your keyboard rows map to the piano keys, so you can play without a mouse. On mobile you simply tap the keys.

Do I need a MIDI keyboard to play?

No. Play with your mouse, your finger on a touchscreen, or your computer keyboard, no hardware required. If you do own a USB MIDI keyboard, plug it in for a more natural feel with velocity and a sustain pedal; the choice is yours.

What if I do not know how to read music?

You do not need to: turn on scale highlighting to see which notes fit the key you are in, or switch to chord mode to play a full chord with a single key. Both make it possible to sound musical from the very first minute, without any theory.
