10th–12th c.

Medieval & Romanesque

Growing monasteries, cathedral schools, and courts supported new ways of making and recording music. Composers expanded existing chant with additional voices, while troubadours and trouvères cultivated vernacular song in aristocratic settings. Hildegard of Bingen wrote distinctive sacred works within monastic life. These traditions coexisted: polyphony enlarged the possibilities of chant rather than making single-line singing obsolete.
