A full piano in your browser
The ManyHand Online Piano gives you all 88 keys of a full-size piano, from the lowest A to the highest C, with nothing to install and no account. Notes fade the way a piano's do — a bass note rings for many seconds, a high one for less than one — and lifting your finger drops the damper and stops the string. Hold the sustain pedal and the notes carry on ringing after you let go, so chords can blend into each other.
The sound is built live in your browser with the Web Audio API rather than played from recordings, so there is nothing to download before the first note.
How to play
- Mouse or touch. Click or tap a key. Each finger plays its own note, and sliding across the keys plays every key you pass over.
- Soft and loud. Where you press matters: near the front edge of a key the note is loud and bright, nearer the top it is soft and mellow.
- Sustain. Hold Space, or turn on the Sustain button to keep the pedal down.
- Moving around. The screen shows part of the keyboard. Use the ◀ ▶ buttons or the ← → keys to move an octave, or drag the frame on the small keyboard above the keys. Key size trades bigger keys for more of them.
- Fill screen. On a phone this turns the keyboard sideways and gives it the whole display.
Playing with the computer keyboard
Two rows of your keyboard are set out like piano keys: a row of letters for the white keys, and the row above it for the black keys that sit between them. The lower octave starts on the first C you can see on screen; the upper octave starts one C higher. The letters are printed on the keys they play.
| Lower octave | White keys C D E F G A B, then C D E:
Z X C V B N M , . / Black keys C♯ D♯ F♯ G♯ A♯, then C♯ D♯: S D G H J L ; |
|---|---|
| Upper octave | White keys C D E F G A B, then C D E F G:
Q W E R T Y U I O P [ ] Black keys C♯ D♯ F♯ G♯ A♯, then C♯ D♯ F♯: 2 3 5 6 7 9 0 = |
The layout follows where the keys sit, not the letters printed on them, so it works the same on AZERTY, QWERTZ and non-Latin keyboards.
Finding your way around 88 keys
The black keys come in groups of two and three, and that pattern is the map. The white key just to the left of any group of two black keys is a C; the white key just to the left of a group of three is an F. From C the white keys run C D E F G A B and then the pattern starts again, eight notes higher — one octave.
Octaves are numbered from the bottom. Middle C is C4, the fourth C from the left, marked on this piano with a small dot; the A above it, A4, is the note orchestras tune to at 440 Hz. A full piano runs from A0 up to C8: seven octaves and a little more, 52 white keys and 36 black.
Tunes to start with
Choose one under Learn a tune and the piano lights the next key and waits for you — there is no clock to keep up with. Listen plays it through first. The eight first tunes below use white keys only except Für Elise, and none needs more than ten white keys side by side, so a phone screen shows every key you need. A dash means hold the note longer.
More tunes in the list
The same list goes on to 31 well-known melodies, each one out of copyright. They are the tune alone, for one hand, and the classical ones are the famous opening rather than the whole piece. Several are moved to a key with fewer black keys than the composer wrote, so the first notes you learn are easy to find. Some range wider than a phone screen; the keyboard follows the lit key as you go.
Scales, chords and sargam on the keys
Pick a key under Key / Sa and a scale or chord under Show on keys, and every key that belongs gets a dot, with a ring on the root. It is a quick way to see why a C major chord is C–E–G, what changes when it becomes minor, or which five notes make a pentatonic scale to improvise on. The ♪ button plays what is shown.
Set Labels to Sargam and the keys are named Sa Re Ga Ma Pa Dha Ni from whichever note you chose as Sa, with lower-case names for the komal (flat) notes and Ma+ for tivra Ma — handy for working out a raga or a film tune on a keyboard.
To hear chords and progressions played for you, try the Chord Player. To train your ear to recognise intervals, there is the Ear Trainer; to write down what you play, the Staff Notation Writer; and to keep time while you practise, the Metronome.
Record and share
Press Record and the take begins on your first note, so there is no silence to trim. Stop, then Play to watch the keys play it back, pedal and dynamics included. Copy link packs the whole take into the link itself — send it to someone and it opens on their screen ready to play. Nothing is uploaded and nothing is stored on a server.
Using a MIDI keyboard
In Chrome, Edge and Firefox you can play from a real keyboard. Plug it in, press Connect under MIDI and allow access when the browser asks. How hard you strike each key and the sustain pedal both come through. Safari does not support MIDI in the browser, so the MIDI control is not shown there.
Frequently asked questions
Is the online piano free?
Yes — completely free, with no sign-up, no download and no watermark.
How do I play with my computer keyboard?
Z X C V B N M are the white keys of the lower octave, with S D G H J as the black keys above them. Q W E R T Y U are the white keys one octave higher, with 2 3 5 6 7 as their black keys. Hold Space for the sustain pedal and use the ← → keys to move the keyboard an octave.
How many keys does it have?
All 88 keys of a full-size piano, A0 to C8. The screen shows a section at a time; the ◀ ▶ buttons, the small keyboard above the keys, or the arrow keys take you to the rest.
Can I play soft and loud notes?
Yes. Press near the front edge of a key for a loud, bright note and nearer the top for a soft one. A MIDI keyboard sends its own key velocity.
Can I record what I play?
Yes. Record, play, then Stop. Play replays the take on the keys, and Copy link puts the whole take into a link you can send to someone. Nothing is uploaded.
Does it work with a MIDI keyboard?
Yes, in browsers that support Web MIDI such as Chrome, Edge and Firefox. Press Connect under MIDI and allow access.
Does it work on a phone?
Yes. Each finger plays its own note and sliding across the keys plays each one. Fill screen turns the phone sideways and gives the keyboard the whole display.
Do I need to install anything?
No. The sound is made live in the browser with the Web Audio API. The only permission ever asked for is MIDI access, and only if you choose to connect a MIDI keyboard.
