A carillon is a musical instrument consisting of a set of bells that are played using a keyboard. Typically found in towers or bell towers, carillons can have anywhere from 23 to over 70 bells, each tuned to specific pitches. The bells are struck by hammers, which are activated by the player's actions on the keyboard, allowing for a wide range of musical expression. Carillons are often associated with churches, universities, and public parks, providing a unique sound that can be heard over long distances. They are used for various purposes, including playing hymns, classical music, and even contemporary tunes, enriching the cultural atmosphere of their surroundings.
