Most prolific composer - Despite his tragically short life, child prodigy Wolfgang Amadeus Mozart (1756-91) completed c. 1,000 major works, making him also one of the fastest composers. One of his later and most popular works is the opera The Marriage of Figaro, seen here performed at the Royal Opera House, Covent Garden, London, United Kingdom in 1987.
