Medieval Europe invented notation while still singing by memory
Medieval music covers Western Europe’s sacred and secular sounds from roughly the sixth to fifteenth centuries—the longest classical era before the Renaissance. Gregorian chant and other mostly vocal genres dominate; new notation systems rose alongside, not instead of, oral tradition.
Liturgy drove early composition; love songs and dances claimed secular space later. Organum added parallel or freer voices to chant, often at fourths or fifths, seeding polyphony. Motets and clausulae elaborated chant segments; by the late 1200s many motets turned worldly. The rule behind parallel organum goes back at least to the ninth-century Musica enchiriadis. Early written examples survive in Aquitanian polyphony, but the biggest trove comes from the Notre-Dame school and its Magnus Liber Organi. Later motets could stack up to three upper voices, each singing its own text, in French or Latin, on subjects from political satire to courtly love.
Italian madrigals prized fluid leading lines and spawned canons called caccie, three-part secular songs in which the two upper voices chase the same tune over a slow instrumental line. Late medieval scribes finally notated some purely instrumental dances—estampie, ductia, nota—though such pages stayed rare.
Musicologists split the era into Early (500 to 1000), High (1000 to 1300) and Late (1300 to 1400) phases, and pair it with the Renaissance as early music, the stretch before the common practice period. Chant sung in a single line ruled the early church, with Gregorian chant the dominant style, while polyphony grew in the high period and was widespread by around 1300. Many medieval instruments survive in modern, more engineered forms: the flute, for example, was then made of wood and could be blown from the side or the end.
