organ sounds are created by forced air blowing into different types of pipes. most pipes are "flue" pipes and operate similarly to the way sound is produced by a policeman's whistle; no moving parts are involved. the metallic pipes seen mounted on top of the wooden boxes at either side of the altar are flue pipes. "reed" pipes produce their sound when air passes by a thin brass reed causing it to vibrate and set up vibrations within the pipe. the tall, tapering pipes located in the west transept to the left of the altar are reed pipes as are the trumpet pipes extending out from the rear wall at the back of the church. variations in pitch and tone are achieved through the shape, size, and materials used in each pipe as well as the amount of air pressure supplied to them. most of the pipes in the saint thomas organ are constructed of a various mixtures of lead and tin. other pipes are made of wood, such as the large bass pipes located in the west transept. the pipes range in size from high and 1/4 inch wide to high and , 6 inches wide.
