A carillonneur is a musician who plays a carillon, a musical instrument consisting of a set of bells that are played using a keyboard. The carillon is typically found in bell towers and produces a rich, resonant sound. Carillonneurs often perform solo or in ensembles, playing a variety of musical styles, from classical to contemporary. To become a carillonneur, one usually undergoes specialized training, often at a conservatory or through mentorship. The art of playing the carillon requires skill in both music and mechanics, as the musician must understand how to control the bells' tones and rhythms effectively. Notable carillons can be found in many cities, often associated with historic buildings or churches.
