Evensong is a church service traditionally held near sunset focused on singing psalms and other biblical canticles. It is loosely based on the canonical hours of vespers and compline. Old English speakers translated the Latin word vesperas as æfensang, which became 'evensong' in modern English. Typically used in reference to the Anglican daily office's evening liturgy, it can also refer to the pre-Reformation form of vespers or services of evening prayer from other denominations, particularly within the Anglican Use of the Catholic Church.
Evening prayer often takes the form of Choral Evensong, such as this service at Westminster Abbey.

Vespers is a liturgy of evening prayer, one of the canonical hours in Catholic, Eastern Orthodox, Oriental Orthodox, and Lutheran liturgies. The word for this prayer time comes from the Latin vesper, meaning "evening".
