In Dulci Jubilo

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.
