Christoph Willibald Ritter von Gluck (2 July 1714 15 November 1787) was an opera composer of the early classical period. After many years at the Habsburg court at Vienna, Gluck brought about the practical reform of opera's dramaturgical practices that many intellectuals had been campaigning for over the years. With a series of radical new works in the 1760s, among them Orfeo ed Euridice and Alceste, he broke the stranglehold that Metastasian opera seria had enjoyed for much of the century.The strong influence of French opera in these works encouraged Gluck to move to Paris, which he did in November 1773.
