How to play
Click, tap or use a pen on any key. On a touchscreen, several fingers play a chord together.
With a mouse, the keys show their computer-key labels.
The keys match the full app: t plays middle C, and Shift plus a key plays the black key just above it, so Shift+t plays C♯4.
The labels on screen show the key for each note. Typing in a field, or holding Ctrl, Alt or Meta, plays nothing.
The keybed shows one to three octaves, depending on the width of your screen: C4 to C5 on a phone, and up to C3 to C6 on a wide screen.
Only keys shown on screen play.
The two sounds
How each instrument makes its sound, with sources.
Organ
Organ pipes sound when pressurized air passes through them, and an organ's stops choose which sets of pipes sound. Each pipe sounds a single pitch, so a set of pipes, called a rank, has one pipe for every note, and a longer pipe sounds lower. Hands play the keyboards, called manuals, and most organs add a pedalboard for the feet.
Harmonium
A harmonium is a reed organ: air from its bellows makes thin metal reeds vibrate. It pushes that air with pressure bellows; the American reed organ draws it through with suction instead.
Both sounds here are sampled, so there are no stops or bellows to set. Play the same chord on each to compare them.
Before you play
About playing here, and what the full app adds.
No. The keybed runs in your browser, with nothing to install and no account.
Sound starts with your first press. If the sound is still loading, the keybed says so, and your next presses play once it's ready. If it can't load, a Try again button appears.
The same keys as in the full app. The number keys 8, 9 and 0 play C3 to E3, the q row continues from F3 and the a row from B4, up to l, which plays C6. Shift plus a key plays the black key just above it: Shift+t plays C♯4. The labels on screen show the key for each note.
Only notes shown on the keybed play. A narrow screen shows one octave, C4 to C5, so keys for other notes stay silent. A wide screen shows C3 to C6.
Yes. On a touchscreen, several fingers sound together. On a computer keyboard, hold several keys; some keyboards limit how many keys register at once.
No. Both sounds are sampled, so there are no stops or bellows to set. The full app adds songs and recording, not organ controls.
Not on this page. Play, the full app on a computer, works with a USB MIDI keyboard.
Songs and recording. It opens on the sound you picked here: Play on a computer with a mouse or trackpad, or the touch piano on a touch device without one. Play has 16 instruments, 61 keys from C2 to C7, and four ways to learn a song: Magic Play, Demo, Play Along and Practice.
