Jean-Baptiste Lully (November 28, 1632 - March 22, 1687) was an Italian-born French baroque style composer, instrumentalist, and dancer who spent most of his life working in the court of Louis XIV of France. His music is known for its power, liveliness in its fast movements and its deep emotional character in its slower movements. The influence of his music produced a radical revolution in the style of the dances of the court itself. He introduced lively ballets of rapid rhythm, often based on well-known dance types such as gavottes, menuets, rigaudons and sarabandes. Through his collaboration with playwright Moli癡re, a new music form emerged during the 1660s: the com矇die-ballet which combined theater, comedy, incidental music and ballet. During a performance of his Te Deum to celebrate Louis XIV's recovery from surgery, Lully seriously injured himself when he struck his foot with his long conducting staff. Refusing to have his leg amputated, so he could still dance, gangrene spread through his body and caused his death in 1687 at the age of 54.
