Ambrosian Chant is a form of liturgical music that originated in the early Christian church, particularly in the region of Milan. It is named after Saint Ambrose, the Bishop of Milan in the 4th century, who is credited with its development. This chant is characterized by its simple melodies and free rhythm, which are designed to enhance the text of the scriptures during worship. Unlike the more widely known Gregorian Chant, Ambrosian Chant features a distinct style that includes the use of different modes and a unique approach to musical phrasing. It is still performed in some churches today, preserving the rich musical heritage of the Ambrosian Rite.
