The Chapel Royal Choir is made up of six Gentlemen-in-Ordinary, ten choristers, an Organist and Choirmaster and a Sub-Organist. The boys are traditionally known as the Children of the Chapel Royal, and wear the distinctive State uniform introduced at the Restoration in 1660. The boys attend City of London School, and receive a Choral Scholarship.
Boys join the Choir as Probationers, becoming full choristers when one of the existing ten choristers leaves.
Boys normally audition for the choir aged 7 or 8, although it is possible for older boys to be considered.
