Serse January, the third by 6 February, and Handel put the finishing touches to the score on 14 February. "Serse" was first performed at the King's Theatre, Haymarket on 15 April 1738. The first production was a complete failure. The audience may have been confused by the innovative nature of the work. Unlike his other operas for London, Handel included comic ("buffo") elements in "Serse". Although this had been typical for 17th-century Venetian works such as Cavalli's original setting of the libretto, by the 1730s an "opera seria" was expected to be wholly serious, with no mixing of the genres of
Baroque music of the British Isles for the Royal Fireworks". His opera, including "Rinaldo" (1711, 1731), "Orlando" (1733), "Ariodante" (1735), "Alcina" (1735) and "Serse" (1738, also known as "Xerxes"), helped make Britain second only to Italy as a centre of operatic production. His sacred drama and choral music, particularly the coronation anthem "Zadok the Priest" (written for the inauguration of George II in 1727) which has remained part of the ceremony for British monarchs, and above all, the "Messiah", helped set the British taste in music for the next 200 years. He was a major influence on future classical composers including Haydn, Mozart and Beethoven. Ballad
