A generic term for a fairly wide variety of reed stops. Usually found at 8' pitch, occasionally 16' in the pedal. See also Tromba. On some (orchestral) instruments, the name may be given to what should more properly be called Orchestral Trumpet. Comes in a wide variety of dynamics and brightness. One builder's gentle Trumpet may be another builder's assertive Oboe.
In its common forms, the Trumpet is usually a versatile stop, usable either as a solo stop or in chorus with principals, mixtures, and/or other chorus reeds. If an organ has only one manual reed stop, it is often a Trumpet, and usually on the Swell. Likewise, if a larger organ contains two different reed stops of the same type, it is likely to be a Trumpet.
Full-length resonators. The bass octave of a 16' stop may have half-length resonators. The illustrations are Audsley's.
Any organ with more than two dozen ranks is nearly certain to have one. No examples are known of Tarantantara.
