The choir regularly tours internationally, has produced numerous recordings, and appears often in television and radio broadcasts.
The earliest historical document relating to the chorus dates from 1402 when a John Dyer was named as the cathedral's organist and chorus-master.
A 1544 statute by Henry VIII of England decreed that the cathedral should have ten boys in the choir and a single organist.
They have also appeared in many television and radio broadcasts, including singing live on BBC1 on Easter morning, and on Christmas Day.
The Girls' Choir was founded in 1999 by Sarah Baldock, and is now under the joint leadership of the Acting Director of Music, Andrew Lucas, and the Sub-organist, Joshua Stephens.
