Where do pipe organs get their air?

How sound is produced. A pipe organ feeds wind into pipes, causing the air to oscillate and produce a sound. The pipes stand in line above the box referred to as the wind-chest, with wind fed from below into the pipes the organist wishes to use to produce sound.

Does an organ have stops?

Stops are arrayed on the organ console, or control board: mechanical stops are usually knobs, and electric stops are usually tabs or buttons.

What is a pipe organ made of?

Materials. Organ pipes are generally made out of either metal or wood. Very rarely, glass, porcelain, plastic, paper, Papier-mâché, or even stone pipes may be seen.

Why do pipe organs have multiple keyboards?

With multiple manuals (the organ term for keyboards), the organist can both create layers of sounds for richer textures, as well as switch between different sounds rapidly. Multiple manuals add to the cost and weight. For smaller organs or even portable organs, multiple manuals are often too much of a liability.
