Play piano. Anywhere.

You can play this online piano three ways: click the keys with your mouse, tap them on a touchscreen, or press the keys on your computer keyboard. Every key sounds the moment you trigger it — there is nothing to load, install, or sign up for. The whole instrument lives on a single page: choose a sound from the tabs above, and the one keyboard below serves all seven instruments. To get started, the middle of the piano keyboard is mapped to the middle of your computer keyboard, so the note C4 sits under M and the surrounding notes sit under the surrounding keys. Hold a key and the note sustains; let go and it rings out and fades on its own, the way a real instrument does.

This virtual piano maps the physical keys of your computer keyboard onto three octaves, from C3 up to B5 — 21 white keys and 15 black keys. It reads the physical key you press, not the character it types, so the mapping is identical whatever your language or keyboard layout. On the default Wide1 layout the middle octave lands under your right hand: C4 = M, D4 = , or Q, E4 = . or W, F4 = / or E, G4 = R, A4 = T and B4 = Y. The octave above keeps going with C5 = U, D5 = I and E5 = O, while the lower octave falls under the left hand from C3 around Z, X, C and V.

Three layouts are available through the Key Layout control at the bottom of the page. Wide1 and Wide2 spread the full three octaves across the whole keyboard for two-handed playing, while Narrow focuses on a single octave, C4 to F5, under the home-row keys A through ' — friendlier for beginners. Switch layouts and the label on every key updates to match. To see exactly which keys form a given sound, the piano chords and piano scales pages highlight the keys for each chord and scale on this same keyboard.

Two controls below the keyboard shift the whole instrument at once. Octave moves every key up or down by a full octave — twelve semitones — in a single step. Reach for it when a melody runs past the top or bottom of the visible keys, or to drop a bass line an octave lower. Transpose shifts every key by one semitone at a time; twelve steps of transpose equal one octave. Transposing is how you play piano online in a different key without relearning the fingering, or accompany a singer whose comfortable range sits a few steps away from the original. Each control shows its current value in the centre, and all seven instruments and all three layouts follow it together.

A real piano has a sustain pedal that lets notes keep ringing after your fingers leave the keys. Here you get the same effect by holding down the Space bar — it works as the right pedal. With Space held, a note you play will not stop the moment you release its key; it keeps ringing and slowly fades, exactly as it would with the pedal down on an acoustic piano. Let go of Space and released notes stop promptly again. It is ideal for slow, flowing passages and for letting one chord melt into the next. The Sustain indicator lights up gold the instant the pedal engages, so you always know its state.

Everything you play can be captured. Press Record and the online piano recorder starts saving your performance — the timer counts up while it listens. Play freely: run a chord progression, improvise over a scale, or keep time with the metronome. Press Record again to stop, then Play to hear it back before you commit. Happy with the take?
