abstract:A contralto is a type of classical female singing voice whose vocal range is the lowest female voice type, with the lowest tessitura. The contralto's vocal range falls between tenor and mezzo-soprano; typically between the F below middle C (F3 in scientific pitch notation) to the second G above middle C (G5), although at the extremes some voices can reach the E below middle C (E3) or the second B above middle C (B5).
