En chamade

The double-faceted baroque organ of the Cathedral of Santiago de Compostella. Notice the en chamade pipes (trumpets) protruding outwards from its lower part.

En chamade (French: "to sound a parley") refers to powerfully voiced reed stops in a pipe organ that have been mounted horizontally, rather than vertically, in the front of the organ case, projecting out into the church or concert hall.[1] They produce a commanding, loud trumpet-like tone, used for fanfares and solos. It is known as Fan Trumpet, Horizontal Trumpet, and Trompette en Chamade.

Any stop mounted en chamade will be much louder than a stop elsewhere in the organ, even though in church organs the stops may stand on the same wind pressure. In theatre and concert organs, en chamade stops often stand on higher wind pressure than the other stops, to sound even more powerful and commanding.[2]
