Jean-Baptiste Lully Jean-Baptiste Lully (] ; born Giovanni Battista Lulli ] ; 28 November 1632 – 22 March 1687) was an Italian-born French composer, instrumentalist, and dancer who spent most of his life working in the court of Louis XIV of France.

Philippe Musard Philippe Musard (8 November 1792 – 31 March 1859) was a French composer who was crucial to the development and popularity of the promenade concert. One of the most famous personalities of Europe during the 1830s and 1840s, his concerts in Paris and London were riotous (in several senses of the word) successes. Best known for his "galop" and "quadrille" pieces, he composed many of these numbers himself, usually borrowing famous themes of other composers. Musard plays an important role in the development of light classical music, the faculty of publicity in music, and in the role of the conductor as a musical celebrity. He has been largely forgotten subsequent to his retirement in the early 1850s.
