An anthem is a musical composition of , usually used as a symbol for a distinct group, particularly the national anthems of countries. Originally, and in music theory and religious contexts, it also refers more particularly to short sacred choral work and still more particularly to a specific form of Anglican church music.
Anthem is derived from the Greek ἀντίφωνα (antíphōna) via Old English antefn. Both words originally referred to antiphons, a call-and-response style of singing. The adjectival form is "anthemic".
Anthems were originally a form of liturgical music. In the Church of England, the rubric appoints them to follow the third collect at morning and evening prayer. Several anthems are included in the British coronation service. The words are selected from Holy Scripture or in some cases from the Liturgy and the music is generally more elaborate and varied than that of psalm or hymn tunes. Being written for a trained choir rather than the congregation, the Anglican anthem is analogous to the motet of the Roman Catholic and Lutheran Churches but represents an essentially English musical form. Anthems may be described as "verse", "full", or "full with verse", depending on whether they are intended for soloists, the full choir, or both.
