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.

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. Mezzo-sopranos are well represented in baroque music, early music, and baroque opera. Mezzos sometimes play dramatic soprano roles such as Santuzza in Mascagni's Cavalleria rusticana, Lady Macbeth in Verdi's Macbeth, and Kundry in Wagner's Parsifal.

The vocal range of the mezzo-sopranos lies between the soprano and the contralto voice types. Mezzo-sopranos generally have a heavier, darker tone than sopranos. The mezzo-soprano voice resonates in a higher range than that of a contralto. The terms Dugazon and Galli-Marié are sometimes used to refer to light mezzo-sopranos, after the names of famous singers. Usually men singing within the female range are called countertenors since there is a lighter more breathy tonal (falsetto) quality difference. In current operatic practice, female singers with very low tessituras are often included among mezzo-sopranos, because singers in both ranges are able to cover the other, and true operatic contraltos are very rare.
