The Franco-Flemish School refers to a succession of Northern European composer-singers from the Low Countries and northern France who, during the 15th and 16th centuries, perfected a richly woven style of vocal polyphony. Centered on sacred forms such as the Mass and motet, and on courtly chansons, their music is characterized by careful control of dissonance, modal counterpoint, cantus-firmus and paraphrase techniques, and—by the later generations—pervasive imitation. Their chapel-trained composers staffed the great courts and cathedrals of Europe and spread a unified, technically rigorous polyphonic practice from Burgundy and the French royal chapels to Italy, Spain, the Empire, and beyond.

Ars subtilior is a late–14th‑century style of Franco‑Flemish and southern French/Iberian court music noted for its extreme rhythmic, notational, and contrapuntal sophistication. It refines the innovations of the Ars nova into music of dazzling subtlety: complex syncopations, multiple simultaneous meters, proportion signs, coloration (red/black notation) that alters rhythmic values, and isorhythmic devices. Composers often wrote in the French formes fixes (ballade, rondeau, virelai) and in elaborate motets, sometimes presenting pieces in fanciful shapes (hearts, circles) to mirror their poetic conceits. The sound world is courtly and intricate: interlocking lines in three or four parts, refined dissonance control, and virtuosic rhythms that challenge performers while serving refined, often allegorical texts.

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.
