The Music for the Royal Fireworks is a suite in D major for wind instruments composed by George Frideric Handel in 1749 under contract of George II of Great Britain for the fireworks in London's Green Park on 27 April 1749. The music celebrates the end of the War of the Austrian Succession and the signing of the Treaty of Aix-la-Chapelle (Aachen) in 1748. The work was very popular when first performed and following Handel’s death. Mozart called the work a “spectacle of English pride and joy.”
