How to play this online piano

Click or tap a key to hear it. On a computer, the middle row of your keyboard plays the white keys from middle C (A, S, D, F, G, H, J, K) and the row above plays the black keys (W, E, T, Y, U). Hold several keys at once to play a chord.

The sound comes from a real piano, recorded note by note: the same one you hear in the Piano One app. The first note can take a second while the piano loads.

Play online with a MIDI keyboard

Connect your MIDI keyboard or digital piano to your computer with a USB cable, then press “Connect a MIDI keyboard”. Every key you play lights up on screen and sounds through the page’s piano. To connect your instrument, open this page in Chrome or Edge on a computer.

Three easy songs to start with

Choose Ode to Joy, Twinkle, Twinkle, Little Star or Mary Had a Little Lamb. The key to play lights up and its name appears above the keyboard. The song waits for you to find the right note, so take your time: speed comes later.

All three melodies use a handful of notes around middle C, which makes them ideal for learning where the keys are.

How the piano keyboard is laid out

The black keys come in groups of two and three. C sits just to the left of every group of two black keys: it is the most useful landmark for finding your way. From one C to the next there are twelve keys, seven white and five black: that is an octave.

The white keys are named C, D, E, F, G, A and B, or Do, Re, Mi, Fa, Sol, La and Si in solfège. Switch the note names above the keyboard to get used to both.

From an online piano to a real one

An online piano is great for discovering the keyboard and picking up a few melodies. But a mouse plays one note at a time, and a computer keyboard cannot feel the weight of the keys or how hard you play: to really learn, nothing replaces a piano or a keyboard.

If you have one, Piano One takes over from here: the app listens to your instrument through your phone’s microphone and guides you note by note, from your first C to your first song. The first lessons are free, with no card and no account.
