Antiphonary

An antiphonary is a specialized liturgical book used in Christian worship, particularly in chanting or singing Psalms, hymns, and other prayers. It contains musical notations and texts organized for antiphons—short chants sung before and after psalms or canticles. Primarily used in monasteries and churches, the antiphonary guides singers through the musical and textual aspects of the service, ensuring coordinated and harmonious worship. It plays a crucial role in preserving the musical tradition of sacred chant, serving as a key resource for monks, priests, and choirs engaged in liturgical practices.
