set to music by many composers. Herbert Howells alone composed 20 settings of the canticles, including his Collegium Regale (1944) and St Paul's (1950) services. Like Mattins, Evensong is a service that is a distinctively Anglican service, originating in the Book of Common Prayer of 1549 as a combination of the offices of Vespers and Compline. Choral Evensong is sung daily in most Church of England cathedrals, as well as in churches and cathedrals throughout the Anglican Communion. It is noted for its particular appeal to worshippers and visitors, attracting both believers and atheists with its meditative quality and cultural value. A service of Choral Evensong is broadcast weekly on BBC Radio 3, a tradition begun in 1926. Preces and responses The Preces (or versicles) and responses are a set of prayers from the Book of Common Prayer for both Morning and Evening Prayer. They may be sung antiphonally by the priest (or a lay cantor) and choir. There are a number of popular choral settings by composers such as William Smith or Bernard Rose; alternatively, they may be sung as plainsong with a congregation. Psalms Morning and Evening Prayer (and sometimes Holy Communion) include a Psalm or Psalms, chosen according to the lectionary of the day. This may be sung by the choir or congregation, either to plainsong, or to a distinctive type of chant known as Anglican chant by the choir or congregation. Anthems or motets Part-way through a service of worship, a choir may sing an anthem or motet, a standalone piece of sacred choral music, which is not part of the liturgy but is usually chosen to reflect to the liturgical theme of the day. Hymns The singing of hymns is a common feature of Anglican worship and usually includes congregational singing as well as a choir. An Introit hymn is sung at the start of a service, a Gradual hymn precedes the Gospel, an Offertory hymn is sung during the Offertory and a recessional hymn at the close of a service. Organ voluntary A piece for organ, known as a voluntary, is often played at the end of a service after the recessional hymn and dismissal. Performance Almost all Anglican church music is written for choir with or without organ accompaniment. Adult singers in a cathedral choir are often referred to as lay clerks, while children may be referred to as choristers or trebles. In
