Master of the Queen's Music, Sir Peter Maxwell Davies, composed three Renaissance Scottish dances that were performed by the Omega Ensemble.
The youngest performer was eight-year-old Vilma Aber Oketta, who played the udu and water drum with the African Abantu Ensemble.
Ian Tindale, a student at Icknield Community College in Oxfordshire, played Bach's Prelude in G Major on the ballroom organ, which was overhauled and recommissioned in 2002.
Buckingham Palace also announced the arrival of a new accolade, the Queen's Medal for Music, which will be bestowed upon individuals who have influenced the nation through music.
The award, open to musicians of any genre, will be awarded on 22 November, the memorial day of the patron saint of music Saint Cecilia.
Sir Peter Maxwell Davies, who will chair the award committee, described the prize as "a concrete symbol of the esteem which most of us feel musical life in Britain deserves".
