The Pipe Organ is a keyboard instrument in which the sound is made by air blowing pipes.
A pipe organ has one or more keyboards (called manuals) played by the hands, and a pedalboard played by the feet; each keyboard has its own group of stops. The keyboard(s), pedalboard, and stops are housed in the organ's console. The organ's continuous supply of wind allows it to sustain notes for as long as the corresponding keys are pressed, unlike the piano and harpsichord whose sound begins to dissipate immediately after it is played. Organs have been made for many centuries. They are usually found in places for Christian worship such as churches and cathedrals, although they may also be found in places like town halls and concert halls or even very large private houses.
