Christoph Willibald Gluck was a composer known for his Italian and French opera during the early classical period. Gluck's notable works include Orfeo ed Euridice and Alceste, which broke the dominance of opera seria. He introduced more drama by using orchestral recitative and shorter arias. Gluck's influence extended to future composers like Mozart, Schubert, and Berlioz. He spent a considerable part of his career in Vienna and later moved to Paris, where he wrote eight operas, with Iphigénie en Tauride being considered his finest work.
