A skilled musician who plays a carillon; a specialist in carillon performance.
From French 'carillon' combined with French masculine occupational suffix '-eur'. This is the standard French spelling, used in English primarily in formal or academic contexts.
The French spelling 'carillonneur' is the most prestigious form of the word—if you're really serious about carillon bells, you use the French version, which adds an air of Old World craftsmanship that the English version somehow lacks.
