サヴォイ・オペラ
The Savoy opera collaborations between Gilbert and Sullivan began in 1875 with "Trial by Jury". They were in the British light opera tradition with spoken dialogue. They reached their heyday in the 1880s with "The Pirates of Penzance" (1880), and "The Gondoliers" (1889), and concluded in 1896 with "The Grand Duke". They had rivals like Alfred Cellier's (1844–91) "Dorothy" (1886) and "The Mountebanks" (1892), but were the most successful operas of the era and have been among the most frequently revived.
