Saint Joseph's Oratory in the context of "Carillon"

A carillon (US: /ˈkærəlɒn/ KARR-ə-lon, UK: /kəˈrɪljən/ kə-RIL-yən) is a pitched percussion instrument that is played with a keyboard and consists of at least 23 bells. The bells are cast in bronze, hung in fixed suspension, and tuned in chromatic order so that they can be sounded harmoniously together. They are struck with clappers connected to a keyboard of wooden batons played with the hands and pedals played with the feet. Often housed in bell towers, carillons are usually owned by churches, universities, or municipalities. They can include an automatic system through which the time is announced and simple tunes are played throughout the day.

Carillons come in many designs, weights, sizes, and sounds. They are among the world's heaviest instruments, and the heaviest carillon weighs over 91 metric tons (100 short tons). Most weigh between 4.5 and 15 metric tons (5.0 and 16.5 short tons). To be considered a carillon, a minimum of 23 bells is needed; otherwise, it is called a chime. Standard-sized instruments have about 50, and the world's largest has 77 bells. The appearance of carillons depends on the number and weight of the bells and the tower in which they are housed. They may be found in towers that are free-standing or connected to a building. The bells of a carillon may be directly exposed to the elements or hidden inside the structure of their towers.
