mezzo-soprano

A mezzo-soprano (, ), or mezzo ( ), is a type of classical female singing voice whose vocal range lies between the soprano and the contralto voice types. The mezzo-soprano's vocal range usually extends from the A below middle C to the A two octaves above (i.e. A3–A5 in scientific pitch notation, where middle C = C4; 220–880 Hz). In the lower and upper extremes, some mezzo-sopranos may extend down to the F below middle C (F3, 175 Hz) and as high as "high C" (C6, 1047 Hz). The mezzo-soprano voice type is generally divided into coloratura, lyric, and dramatic.

== 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 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.
