A comprimario is a small supporting role in an opera[1] (or a singer who sings those roles).[2] The word is derived from the Italian "con primario", or "with the primary", meaning that the comprimario role (or singer) is not a principal role (or singer).[3] The term usually refers to characters who do not sing any full-length arias or long scenes (although mute characters, who do not sing at all, are not considered comprimarios).
Many singers began their careers as comprimario singers; many others end their careers that way when they become too infirm to cope with long roles; some have made a career out of singing such parts. Among these latter are singers such as Piero de Palma, Anthony Laciura, Jean Kraft, Nico Castel, and Charles Anthony of the Metropolitan Opera; others include Plinio Clabassi, Ernesto Gavazzi and Karl Dönch.
