Vivaldi: Stabat mater; Nisi Dominus; Salve Regina

The classical countertenor is a male singing voice that utilizes a developed falsetto or head voice technique to sing in the alto, mezzo-soprano, or soprano range, typically spanning from G3 to E5 or F5. Historically associated with the 'contratenor altus' line in early polyphony and later the English cathedral tradition, the modern genre emerged as a solo art form in the mid-20th century. It is characterized by a pure, often vibrato-less, and ethereal tone that distinguishes it from female voices in the same range. While the repertoire is heavily rooted in the Baroque era (originally written for castrati), the genre has expanded to include Renaissance lute songs, contemporary classical compositions, and art songs.
