contralto

n. (Music) low alto, voice range between soprano and tenor; singer with a contralto voice

In music, an alto or contralto is a singer with a vocal range somewhere between a tenor and a mezzo-soprano. The term is used to refer to the lowest female singing voice, or to a kind of male singing voice utilizing falsetto called a countertenor. Alto pieces normally span between G below middle C to the E a tenth above middle C (i.e. G3-E5). At the bottom of their range, male altos sound almost like tenors. Some altos have even larger ranges; from the C below middle C to the C two octaves above (C3-C6 if middle C is C4), but like all singers, their vocal type is defined mostly by their "vocal center" and not by their range (a soprano for instance could technically possess the lower range of an alto, but would not be comfortable singing it). In four part choral harmony, the alto is the second highest voice. Alto pieces were originally written in the alto clef, but now use the treble clef.
