The "Carillon" is an musical instrument having up to four dozen bells of various sizes. The bells sound as a hymn or as a celebratory peal when they are triggered by the touch of keys on a board, similar to a piano keyboard.
The sound of the carillon is also called carillon. The name comes from French, "quatrillon". The arrangement for the bells within a church bellfry is with equal numbers facing north, south, east, and west: the four corners of the world.
Typical times to sound the carillon are at midnight as Easter begins, at Christmas, and as a newly-married couple leaves the church. Other times are to signal danger, and during a funeral, as the body leaves the church on the way to the graveyard. For funerals, the sound is more mournful than celebratory.
A similar instrument is the German Glockenspiel, literally "bell-play".
