A carillonneur is a musician who plays the carillon, a musical instrument consisting of a set of bells that are played using a keyboard. The carillon is often found in bell towers and produces a rich, resonant sound. Carillonneurs typically perform a variety of music, from classical pieces to contemporary tunes, and their performances can be enjoyed by the public. To become a carillonneur, one usually undergoes specialized training, often at a conservatory or through mentorship with an experienced carillonneur. The art of playing the carillon requires skill in both music and mechanics, as the musician must understand how to control the bells' striking mechanisms effectively.
