Tremulants create a change in pitch (sharp and flat), amplitude (volume) and timbre (tone
quality). The use of the tremulant adds warmth to solo or small ensemble combinations. It is not
common to use tremulants in larger classical ensembles. In some romantic ensembles,
tremulants are used judiciously. In some gospel and evangelical musical traditions, tremulants

There are two types of tremulant controls on the Rodgers T837. The Divisional tremulants
(Great, and Swell) affect only the stops in the respective division. The Swell trem also controls a
separate trem for the Voix Humaine. There are two General tremulants: the FLT VIB tremulant
affects all manual flute stops simultaneously, and the Main II tremulant affects all remaining
manual stops simultaneously.
All tremulants may be individually adjusted for rate and depth by performing the following
procedure:
