Boy soprano is a vocal category rather than a single stylistic genre: it refers to pre‑pubescent male singers who carry the soprano (treble) line, typically with a bright, pure, and largely straight‑toned sound.
Historically associated with European sacred music—cathedral and monastery choirs in particular—the boy soprano voice became the default treble sonority in Anglican and many Catholic institutions. The repertoire spans chant, Renaissance polyphony, Baroque anthems and motets, Classical and Romantic liturgical works, and modern anthems and carols, as well as selected opera roles and concert works written for a boy treble soloist.
In performance, the timbre favors clarity of diction, purity of line, light vibrato (if any), and a comfortable tessitura in the upper treble. Accompaniment ranges from unaccompanied choral textures to organ, chamber ensembles, and full orchestra.
