Sir Michael Kemp Tippett (2 January 1905 – 8 January 1998) was an English composer who rose to prominence during and immediately after the Second World War. In his lifetime he was sometimes ranked with his contemporary Benjamin Britten as one of the leading British composers of the 20th century. Among his best-known works are the oratorio A Child of Our Time, the orchestral Fantasia Concertante on a Theme of Corelli, and the opera The Midsummer Marriage.
Tippett's talent developed slowly. He withdrew or destroyed his earliest compositions, and was 30 before any of his works were published. Until the mid-to-late 1950s his music was broadly lyrical in character, before changing to a more astringent and experimental style.
