The pipe organ is a keyboard instrument in which the sound is made by air blowing through pipes. A person who plays the organ is called an organist. The organist plays the instrument using both the hands and the feet. The hands play the keyboards (called manuals), while the feet play pedals which also make notes.
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 large private houses. Very small organs can be called “chamber organs”. Organs in large churches, cathedrals or halls are very large instruments indeed, and are built especially for the building they are in. They are called “pipe organs” to distinguish them from modern “electronic organs”.
No two organs are ever quite the same, and they vary greatly from one country to another and one historical period to another. The information here is about organs from Europe, Great Britain and America.
