Britten was an English composer, conductor and pianist. He was a central figure of 20th-century British classical music, with a range of works including opera, other vocal music, orchestral and chamber pieces. His best-known works include the opera Peter Grimes (1945), the War Requiem (1962) and the orchestral showpiece The Young Person's Guide to the Orchestra (1945).
Together with Pears and the librettist and producer Eric Crozier, Britten founded the annual Aldeburgh Festival in 1948, and he was responsible for the creation of Snape Maltings concert hall in 1967. In his last year, he was the first composer to be given a life peerage.

Britten's other works range from orchestral to choral, solo vocal, chamber and instrumental as well as film music. He took a great interest in writing music for children and amateur performers, including the opera Noye's Fludde, a Missa Brevis, and the song collection Friday Afternoons. He often composed with particular performers in mind. His most frequent and important muse was his personal and professional partner, the tenor Peter Pears; others included Kathleen Ferrier, Jennifer Vyvyan, Janet Baker, Dennis Brain, Julian Bream, Dietrich Fischer-Dieskau and Mstislav Rostropovich. Britten was a celebrated pianist and conductor, performing many of his own works in concert and on record. He also performed and recorded works by others, such as Bach's Brandenburg concertos, Mozart symphonies, and song cycles by Schubert and Schumann.
