Gregorian chant is the central Western tradition of plainchant: a monophonic, unaccompanied sacred song in Latin (and occasionally Greek) used in the Roman Catholic liturgy. It employs free rhythm guided by the prosody of the text rather than by strict meter, and is sung in unison by clerics or scholas. Its melodies are organized by the system of eight church modes, with characteristic finalis (final), tenor/reciting tones, and melodic formulas. Repertoires include the Proper and Ordinary of the Mass (e.g., Introit, Gradual, Alleluia, Offertory, Communion, Kyrie, Gloria, Credo, Sanctus, Agnus Dei) and the Divine Office (e.g., Antiphons, Responsories, Hymns, Psalms). Although legend credits Pope Gregory I, modern scholarship sees Gregorian chant as a Carolingian synthesis of Old Roman and Gallican chants, standardized across Frankish realms and later the broader Latin West.

Old Roman chant is a Medieval Latin plainchant tradition associated with the papal liturgy in Rome before the universal adoption of Gregorian chant. Preserved in 11th–12th‑century manuscripts yet reflecting much earlier practice, it represents a distinct Roman repertory rather than a mere variant of the later Gregorian standard. It is monophonic, a cappella, and modal, typically more melismatic and ornate than most Gregorian melodies. The chant follows the accent and syntax of sacred Latin texts with a flexible, speech‑like rhythm. It was performed by trained clerical choirs (scholae cantorum) within the Mass and Office, using formulaic melodic patterns (centonization) and the eight ecclesiastical modes.

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.

Choral refers to music written for and performed by a choir—an ensemble of voices organized into sections such as soprano, alto, tenor, and bass (SATB), or same-voice groupings (SSA, TTBB). It encompasses both sacred and secular repertoire and may be sung a cappella or with accompaniment by organ, piano, or full orchestra. Stylistically, choral music ranges from chant-like monophony to intricate polyphony and rich homophonic textures. Texts are drawn from liturgy, scripture, poetry, and vernacular sources, and are set in many languages. Performance contexts include church services, concert halls, and community events, making choral one of the most socially embedded and widely practiced forms of ensemble music. Across history, choral music has served as a laboratory for vocal counterpoint, word painting, and text-driven form, while functioning as a cultural bridge among religious rites, national traditions, and contemporary concert practice.

Ambrosian chant is the liturgical plainchant of the Ambrosian Rite, practiced primarily in and around Milan, Italy. It is one of the few non-Gregorian Latin chant traditions to survive in continuous use, and is closely associated with the legacy of St. Ambrose (4th century). Like other plainchant, it is monophonic, unaccompanied, and sung in Latin, but it has its own melodic idioms, modal organization, and liturgical genres distinct from the Roman (Gregorian) tradition. Its rhythms are free and speech-like, designed to carry sacred texts clearly and reverently rather than follow metrical patterns. Ambrosian hymnody, often in iambic dimeter, is a hallmark, reflecting the formative influence of early Milanese practice and Eastern antiphonal singing.
