Liturgical music originated as a part of religious ceremony, and includes a number of traditions, both ancient and modern. Liturgical music is well known as a part of Catholic Mass, the Anglican Holy Communion service (or Eucharist) and Evensong, the Lutheran Divine Service, the Orthodox liturgy, and other Christian services, including the Divine Office. The qualities that create the distinctive character of liturgical music are based on the notion that liturgical music is conceived and composed according to the norms and needs of the various historic liturgies of particular denominations.
