King Arthur, or The British Worthy is a semi-opera in five acts with music by Henry Purcell and a libretto by John Dryden. It was first performed at the Queen's Theatre, Dorset Garden, London, in late May or early June 1691. The plot is based on the battles between King Arthur's Britons and the Saxons, rather than the legends of Camelot (although Merlin does make an appearance).
Henry Purcell (1659-1695) is generally considered to be one of the greatest English composers.He incorporated Italian and French stylistic elements into his compositions, written during the Baroque period. Henry Purcell's family lived just a few hundred yards west of Westminster Abbey. Henry Purcell Senior was a gentleman of the Chapel Royal and sang at the coronation of King Charles II of England. Purcell is said to have been composing at nine years old. Purcell died in 1695 at his home in Dean's Yard, Westminster, at the height of his career. He is believed to have been 35 or 36 years old at the time. The cause of his death is unclear: one theory is that he caught a chill after returning home late from the theatre one night; another is that he died of tuberculosis. Purcell is buried adjacent to the organ in Westminster Abbey. The music that he had earlier composed for Queen Mary's funeral was performed during his funeral. In 1691, he wrote the music for what is sometimes considered his dramatic masterpiece, “King Arthur”. One year later, he composed “The Fairy-Queen” based on Shakespeare's “A Midsummer Night's Dream”, the score of which was rediscovered in 1901. “The Indian Queen” followed in 1695. Purcell also had a strong influence on English composers of the mid 20th century, most notably Benjamin Britten, whose "The Young Person's Guide" to the Orchestra is based on the Rondeau from Purcell's “Abdelazar”.
