Trinity’s gallery and chapel organs were built by Noack Organ and Company of Georgetown, Massachusetts, the chapel instrument dedicated in November, 1967 and the Nave organ dedicated in March, 1969.
The gallery instrument contains forty-one stops in four divisions. The uppermost division is the Great, placed so its sound can best travel into the room to support congregational singing. The Positiv – located in the center, just below the Great – contains more delicate and spicy sounds, such as the Trompette-en-Chamade, a brilliant trumpet stop. The Swell division is directly below the Positiv. Its pipes are enclosed behind swinging shutters, which control the loudness of the sound reaching the listener.
The Pedal division embraces the organ on both sides with its Principal 16’ of solid tin in front. The key desk has been placed a comfortable distance away from the case to allow the player to hear better and be seen by the choir. The keys are made from ebony and rosewood. The key action is the time honored mechanical (tracker) action in which there is a direct mechanical linkage from the player’s fingers to the valves that feed the pipes.
