Legacy of Christoph Willibald Gluck
During Gluck’s lifetime, and in the perceptions of the next generation, he was seen to play a central role in the forging of a new operatic style. Thus, E.T.A. Hoffmann ranked him among the Romantics. Many, however, starting with Handel (as noted above), have found his technique severely flawed and credit his central achievements principally to his adventurous collaborators, Angiolini and Calzabigi. Perhaps, as has been suggested, his musical failings served the needs of these and other reform sensibilities (including his own) better than a more accomplished technique might have. Despite the unevenness of his work, there are countless moments in Gluck that rank among the most powerful and affecting in all of opera, e.g., “Che farò senza Euridice” in Orfeo and “O malheureuse Iphigénie” in Iphigénie en Tauride. Although he had no great successors (for he was soon overshadowed by Mozart, who pursued a much different path), his historical position is assured through his efforts to overturn the outmoded conventions of opera seria without destroying the genre itself and through the model his reform movement would provide later operatic reformers.
