Medieval classical music refers to the body of sacred and secular art music created in Europe from roughly the 5th to the late 15th centuries. It encompasses the Christian chant traditions of the early Middle Ages, the emergence of notated polyphony in the High Middle Ages, and the rhythmically and formally sophisticated Ars Nova of the 14th century.
At its core are modal melodies (church modes), primarily vocal textures, and a gradual evolution from monophony (single melodic line) to increasingly complex polyphony. Notation develops from adiastematic neumes to staff-based pitch notation and, later, mensural systems that codify rhythm. Characteristic sonorities emphasize perfect consonances (octaves, fifths, and fourths), with triadic harmony only beginning to coalesce near the end of the period.
Though rooted in the liturgy (Mass, Office, and Latin song), the era also nurtured rich vernacular traditions—troubadours, trouvères, Minnesänger—and instrumental practices on harp, vielle, recorder, lute, and organ. The period laid the foundational techniques, theories, and repertories that define the entire subsequent Western classical tradition.
Choose a mode and craft a chant-like cantus with stepwise motion and narrow ambitus.
•If writing organum, fix the tenor (chant) and add upper voices: florid melismas over sustained notes (organum purum) or measured discant in rhythmic modes.
•For Ars Nova motet, design an isorhythmic tenor and layer motetus/triplum with differentiated texts, ensuring cadences on modal finals.
•In secular songs, set strophic poetry; use refrain structures (Rondeau) and balanced phrases, cadencing with open fifths/octaves (earlier) or with Landini/double-leading-tone cadences (later).
•Notation: Emulate neumatic/mensural conventions in appearance and rhythmic logic; avoid tonal progressions and dominant–tonic clichés.
