How do Organs Work?
Note: The pictures linked below are of the Allen organ in the York Rite Memorial Chapel
at the Masonic Home for Children in Oxford, North Carolina.
The Player: An organist plays the organ using its console, which resembles a piano keyboard with several exceptions:
The Sound: Pipe organs create sound through, well, pipes. The following pages are part of a larger organ revival site by Marya J. Fancey at the University of Florida, and offer excellent explanations of the different facets of the organ:
The Mechanics: Several sites offer well-written diagrams on the workings o f present-day pipe organs, and offer looks back into older organs from times gone by.
- Organ consoles typically have more than one keyboard.
- Banging harder on organ keys will not increase the volume of the sound the organ generates -- the organist selects the combination of sounds by pulling drawbars -- more on this below.
- There is no sustain pedal as on a piano, which makes playing music smoothly much more difficult. Pianists who are unfamiliar with the organ really miss this. To compensate for this loss, organists gain the use of a pedalboard, a much larger version of a keyboard. To the beginning organist, though, this extra set of keys to worry about can be much more of a hindrance than a help.
