What is an organ?
An organ makes sound differently from a piano. Instead of a hammer striking a string, it sustains each note continuously for as long as you hold the key. A tonewheel organ (the Hammond) does this with spinning metal wheels that generate pure tones, blended into a rich, harmonically dense sound; a pipe organ pushes air through pipes. Either way, the defining feature is sustain — an organ note holds steady and never decays on its own.
The online organ here uses a real sampled organ, so every key holds that same full, continuous tone with no fade — the opposite of a piano or music box, where every note decays.
What does an organ sound like?
An organ sounds full, sustained and harmonically rich. Because the tone never decays, held notes build into a thick, continuous wall of sound, and chords take on a weighty, ceremonial quality that a decaying instrument like a piano simply cannot match. It is the voice of gospel, hymns, anthems, classic rock and the grand cinema organ.
That infinite sustain also makes the organ a powerful teacher of legato phrasing: since a note only stops when you release the key, you control exactly how smoothly one note connects to the next. Try it on the chords page — hold a chord on the organ and it fills the room.
Why play an organ online?
A real organ — whether a tonewheel Hammond with its heavy cabinet and Leslie speaker, or a full church pipe organ — is among the least practical instruments to own. An online organ makes that majestic sound reachable to anyone:
- Play hymns, anthems and sustained pads without buying or housing an instrument.
- Layer held chords into a thick bed of sound, then shift them with Octave and Transpose.
- Hold Space as a sustain pedal for even longer, blended passages.
- Record your performance and download it as an MP3, entirely in your browser.

How to play the organ on your keyboard
Play the organ with your mouse, your touchscreen, or your computer keyboard. Middle C (C4) sits under the M key, and the surrounding notes fan out from there. Because the organ sustains for as long as you hold a key, it is perfect for slow, held chords — press the highlighted keys below and let them ring. Use Play notes to hear a full organ chord.
Songs and chords that suit the organ
The organ is at its best on hymns, anthems and any music built on sustained, full-bodied chords. Try Ode to Joy or Canon in D for a grand, ceremonial colour, and explore the major and minor chords that sound fullest when held. The complete piano chords reference is highlighted on the same keyboard.
The other six instruments
The organ is one of seven real instruments sharing one keyboard here. For a different mood, head back to the online piano and try the Music Box, Marimba, Harp or Rhodes — plus the piano and synth.
