The jilted lover, the tragic artist, the wily prince, the leading man: Tenors take on some of the most prominent and enduring roles in operas of all eras, and are perpetually in high demand for concert performance. Music written for the tenor voice is among the most recognisable to audiences far beyond the opera house and concert hall. Generations of composers, particularly in Italy, understood exactly how to deploy this powerful voice type for maximum emotional impact. Wagner actually created another demanding repertoire for it, often requiring the vocal heft of the so-called Heldentenor.
