Antiphon

An antiphon (Greek ἀντίφωνον, ἀντί "opposite" and φωνή "voice") is a short chant in Christian ritual, sung as a refrain. The texts of antiphons are the Psalms. Their form was favored by St Ambrose and they feature prominently in Ambrosian chant, but they are used widely in Gregorian chant as well. They may be used during Mass, for the Introit, the Offertory or the Communion. They may also be used in the Liturgy of the Hours, typically for Lauds or Vespers. They should not be confused with Marian antiphons or processional antiphons. When a chant consists of alternating verses (usually sung by a cantor) and responses (usually sung by the congregation), a refrain is needed. The looser term antiphony is generally used for any call and response style of singing, such as the kirtan or the sea shanty and other work songs, and songs and worship in African and African-American culture. Antiphonal music is that performed by two choirs in interaction, often singing alternate musical phrases. Antiphonal psalmody is the singing or musical playing of psalms by alternating groups of performers. The term "antiphony" can also refer to a choir-book containing antiphons. The chant of early Christianity through to the end of the 5th century had its root in the Synagogue, whence early Christians borrowed the traditions of the chanting of psalms, singing of hymns and cantillation. There is some evidence from Acts of the Apostles that early Christians stayed close to contemporary Jewish traditions, for example Acts 2:46-47 states that "with one accord in the Temple, and breaking bread from house to house did eat their meat with gladness and singleness of heart, praising God, and having favour with all the people". Socrates of Constantinople wrote that antiphony was introduced into Christian worship by Ignatius of Antioch (died 107) after he saw a vision of two choirs of angels. Antiphonal singing was an element of Jewish liturgy believed to have entered the monasteries of Syria and Palestine in the 4th century from the Jewish communities such as the one in Antioch.
