Handel: Giulio Cesare

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.

Classical contralto refers to the lowest standard female voice type in Western classical music, with a rich, dark timbre and a comfortable tessitura centered in the lower middle register. Typical written range spans roughly E3–F5 (or even down to C3 for true contraltos), with the most resonant, characteristic sound in the low and low‑middle range. The contralto voice is heard in opera, oratorio, cantata, lieder/art song, and symphonic choral repertoire. It often embodies characters of gravitas—mothers, sorceresses, noble confidantes—or delivers contemplative and devotional solos in sacred works. Stylistically, contraltos excel at sustained legato, chiaroscuro shading, and text‑centered delivery; in Baroque music they also negotiate tasteful ornamentation with a dignified, grounded color that differs from the brilliance of soprano or the warmth of mezzo-soprano.
