Gallican chant is the body of liturgical plainchant associated with the Gallican rite practiced in early medieval Gaul (roughly modern France and adjacent regions) before the Carolingian reforms. It is monophonic, unaccompanied sacred vocal music in Latin, intended for the Mass and Office. While only fragmentary musical sources survive, contemporary accounts and later comparative musicology suggest a highly ornate, melismatic style with certain Eastern (Byzantine) inflections and distinctive local liturgical usages. Gallican chant is historically important because its encounter and fusion with imported Roman chant in the late 8th–9th centuries helped give rise to the repertory we now call Gregorian chant.

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.
