A contralto (Italian pronunciation: [konˈtralto]) is a type of classical female singing voice whose vocal range is the lowest female voice type.The contralto's vocal range is fairly rare; similar to, but different from the alto, and almost identical to that of a countertenor, typically between the F below middle C (F3 in scientific pitch notation) to the second F above middle C (F5), although at the extremes some voices can reach the E below middle C (E3) or the second B♭ above middle C (B♭5). The contralto voice type is generally divided into the coloratura, lyric, and dramatic contralto.
