The highest male voice, which was mainly used in very early opera and oratorio (a genre of classical vocal music similar to opera but generally based on a religious topic and accompanied by a choir). The voice of a countertenor sounds very much like a mezzo-soprano’s voice and they often sing the same repertoire. Like the contralto, true countertenors are very rare.
Famous Counter-tenors:Mandreas Scholl, David Daniels, Derek Lee Ragin
