Ars antiqua is a medieval European musical style that flourished roughly from the late 12th century to the early 14th century, with its center of gravity in Paris and the Notre Dame Cathedral school. It is defined by the consolidation of measured rhythm through the six rhythmic modes, the cultivation of polyphony in organum and discant styles, and the emergence of the early motet and conductus. Composers favored two to four vocal parts, with a chant-derived tenor forming the foundation and upper voices providing melismatic and texted counterpoint. Harmony emphasized perfect consonances (unisons, fourths, fifths, and octaves), with cadences carefully prepared. Ars antiqua laid crucial groundwork for European notation (including Franconian mensural concepts), enabling more precise rhythmic coordination and setting the stage for the innovations of the later Ars nova.

Medieval lyric poetry refers to the monophonic, poet-composer song traditions that flourished in medieval Europe, especially from the 12th to the 14th centuries. It centers on refined, metrically crafted texts set to memorable modal melodies and performed by court poets, minstrels, or itinerant singer-poets. The genre is best known through the Occitan troubadours and northern French trouvères, but related traditions also thrived among the German Minnesänger and the Galician‑Portuguese cantigueiros. Typical themes include courtly love (fin'amor), longing and absence, moral or political commentary (sirventes), crusade songs, and nature imagery, articulated through strict stanzaic forms, elaborate rhyme schemes, and refrains. Performance was usually solo voice accompanied by medieval instruments (vielle, harp, lute, psaltery, flutes), with a predominantly syllabic text setting, modal pitch organization (e.g., Dorian, Mixolydian), and strophic repetition that highlighted poetic 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.
