Arcangelo Corelli was an Italian composer, musician, and violinist of the middle Baroque era. His music was key in the development of the modern genres of sonata and concerto, in establishing the preeminence of the violin, and as the first coalescing of modern tonality and functional harmony. February 17, 1653 – January 8, 1713; died at 59. Alive at the same time as Isaac Newton, Voltaire, John Locke, Rembrandt, and Louis XIV of France. Wiki link
