Answer:
Liturgical music arose from religious ceremonies and encompassed a variety of ancient and current traditions. Catholic Mass, Anglican Holy Communion (or Eucharist), Lutheran Divine Service, Orthodox liturgy, and other Christian ceremonies, including the Divine Office, feature liturgical music. The features that give liturgical music its specific character are founded on the idea that it is created and composed following the standards and needs of numerous historic liturgies of different denominations.
Non-liturgical music, in contrast to liturgical music, is created for concert purposes rather than for church rituals, despite its religious themes or lyrics. They may only perform on certain occasions, like feast days, if the parish priests agree.
