Micrologus

Medieval ensemble is a modern performance genre devoted to the historically informed presentation of European music from the Middle Ages (roughly the 9th–15th centuries). Ensembles typically employ reconstructed period instruments (vielle, rebec, lute, harp, psaltery, hurdy‑gurdy, organetto, recorders, shawms, bagpipes, frame drums) and historically grounded vocal techniques to render chant, monophonic song, and early polyphony. Repertoire commonly spans sacred and secular traditions: Gregorian and other plainchants; Notre Dame organum and conductus; ars antiqua and ars nova motets; laude and cantigas; troubadour/trovière songs in Occitan and Old French; and instrumental dances such as estampies, ductias, saltarelli, and caroles. Performances prioritize modal pitch systems, medieval rhythmic practice (modal rhythms, isorhythm), open-fifth sonorities, and language authenticity (Latin, Occitan, Old French, Middle English, Galician‑Portuguese).

Medieval music refers to the diverse sacred and secular musical practices of Europe between the fall of the Western Roman Empire and the dawn of the Renaissance. It spans more than eight centuries, from early monophonic chant to the first notated polyphony. Core features include the use of church modes rather than major/minor, extensive reliance on vocal music (Latin sacred chant as well as vernacular song), and the progressive development from unmeasured chant to rhythmic modal notation and, later, mensural notation. Texture evolves from monophony (plainchant, troubadour songs) to organum, conductus, and the motet, culminating in complex isorhythmic works by the late 13th–14th centuries. Secular traditions—troubadours and trouvères in France, Minnesänger in German lands, and the Iberian Cantigas—coexisted with and influenced sacred practice. Instruments such as the vielle, harp, psaltery, recorder, shawm, hurdy-gurdy, and portative organ often doubled or accompanied voices, though much music remained purely vocal.
