An Antiphonary, Antiphonal, or Antiphoner (Latin antiphonarium, antiphonarius, antiphonarius liber, antiphonale; Greek ’antíphonon, antiphon, antiphone, anthem) is one of the present liturgical books intended for use in choro (i. e. in the liturgical choir), and originally characterized, as its name implies, by the assignment to it principally of the
antiphons used in various parts of the Roman
liturgy.
