Mezzo-soprano [SEP] History
While mezzo-sopranos typically sing secondary roles in operas, notable exceptions include the title role in Bizet's "Carmen", Angelina (Cinderella) in Rossini's "La Cenerentola", and Rosina in Rossini's "Barber of Seville" (all of which are also sung by sopranos, and the latter two by contraltos). Many 19th-century French-language operas give the leading female role to mezzos, including "Béatrice et Bénédict", "La damnation de Faust", "Don Quichotte", "La favorite", "Dom Sébastien", "Charles VI", "Mignon", "Samson et Dalila", "Les Troyens", and "Werther", as well as "Carmen". Typical roles for mezzo-sopranos include the stereotypical triad associated with contraltos of "witches, bitches, and britches": witches, nurses, and wise women, such as Azucena in Verdi's "Il trovatore"; villains and seductresses such as Amneris in Verdi's "Aida"; and "breeches roles" or "trouser roles" (male characters played by female singers) such as Cherubino in Mozart's "Le nozze di Figaro".
