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.

Baroque violin refers both to the instrument in its Baroque setup and to the repertory and performance practice for violin from roughly 1600–1750. Typical instruments use gut strings, a lighter bass bar, a shorter/shallower neck angle, and no chin- or shoulder-rest. They are paired with a Baroque bow, whose camber and weight distribution encourage speech‑like articulation, sprung strokes, and a clear attack/decay. Pitch is commonly at A≈415 Hz (varying by region), and temperaments may be circulating or meantone rather than modern equal temperament. Stylistically, Baroque violin playing emphasizes rhetorical phrasing (the "Doctrine of Affections"), ornamental vibrato (used as a coloristic embellishment rather than a constant), extempore ornamentation, and expressive bowing. The music lives in sonatas (da chiesa/da camera), dance suites, concerti (including the concerto grosso), and theatrical or sacred contexts, nearly always underpinned by basso continuo.
