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.

Renaissance music (c. 1400–1600) marks the shift from medieval sonorities to a clearer, triad-based polyphony in which multiple independent voices are treated with near-equal importance. It favors modal counterpoint, pervasive imitation, smooth voice-leading, and carefully prepared cadences. Text intelligibility and expressive text-setting become central concerns, especially in sacred motets and masses and in secular forms like the Italian madrigal and the French chanson. While much of the repertory is a cappella, instrumental consorts (viol, recorder, sackbut, cornett, organ) play a growing role. A steady tactus underpins rhythms, and tuning systems such as meantone temperament shape its characteristic color. Music printing (from 1501) accelerates stylistic diffusion across Europe.

Ars nova is a 14th‑century European musical style that originated in France and spread to Italy, marking a decisive break from the earlier Ars antiqua. It is distinguished by innovations in rhythmic and mensural notation that allowed composers to write complex, syncopated, and independently moving parts. Typical genres and forms include the isorhythmic motet, mass movements, and secular chansons in the formes fixes (ballade, virelai, and rondeau). Textures are primarily vocal and polyphonic (often three to four voices), with techniques such as isorhythm (talea and color), hocket, and frequent use of mensural proportions. Its French wing coalesced around the theories and works of Philippe de Vitry and Guillaume de Machaut, while the Italian Trecento (often considered an Italian Ars nova) cultivated parallel secular song forms and characteristic cadences (e.g., the Landini cadence).

A motet is a polyphonic vocal composition, usually on a sacred Latin text, that emerged in the High Middle Ages and became a central genre of European art music during the Renaissance. Early motets layered different texts and rhythms above a chant-derived tenor, while later Renaissance motets favored smooth, imitative counterpoint shared among voice parts. Across its long history the motet served both liturgical and devotional functions, typically performed a cappella by small choirs. Stylistically it ranges from the rhythmically intricate, isorhythmic constructions of the 13th–14th centuries to the balanced, text-sensitive writing of the 16th century, and onward to concerted and chorale-based treatments in the Baroque and beyond.

Classical music is the notated art-music tradition of Europe and its global descendants, characterized by durable forms, carefully codified harmony and counterpoint, and a literate score-based practice. The term “classical” can refer broadly to the entire Western art-music lineage from the Medieval era to today, not just the Classical period (c. 1750s–1820s). It privileges long-form structures (such as symphonies, sonatas, concertos, masses, and operas), functional or modal harmony, thematic development, and timbral nuance across ensembles ranging from solo instruments to full orchestras and choirs. Across centuries, the style evolved from chant and modal polyphony to tonal harmony, and later to post-tonal idioms, while maintaining a shared emphasis on written notation, performance practice, and craft.

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.
