Mezzo-soprano range so its soprano

A mezzo-soprano or mezzo (meaning "half soprano") 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). In the lower and upper extremes, some mezzo-sopranos may extend down to the F below middle C (F3) and as high as "high C" (C6).
