The Choir of Salisbury Cathedral exists to sing services in Salisbury Cathedral, Wiltshire, England, and has probably been in existence since the consecration of the cathedral in 1258. The choir comprises twenty boy choristers and twenty girl choristers aged from 8 to 13 years and six professional Lay Vicars singing countertenor, tenor and bass. Salisbury Cathedral was the first English cathedral to recruit girl choristers (in 1991) and, when in the cathedral, the girls' choir is usually wholly independent of the boys'. The weekly services are equally divided between the boy and girl choristers throughout the school year.
