Riccardo Eugenio Drigo (Russian: Риккардо Эудженьо Дриго) (30 June 1846 – 1 October 1930) was an Italian composer of ballet music and Italian opera, a theatrical conductor, and a pianist.
Drigo is most noted for his long career as kapellmeister and Director of Music of the Imperial Ballet of Saint Petersburg, Russia, for which he composed music for the original works and revivals of the choreographers Marius Petipa and Lev Ivanov. Drigo also served as Chef d'orchestre for Italian opera performances of the orchestra of the Imperial Mariinsky Theatre. During his career in Saint Petersburg, Drigo conducted the premieres and regular performances of nearly every ballet and Italian opera performed on the Tsarist stage.
Drigo is equally noted for his original full-length compositions for the ballet as well as his large catalog of supplemental music written ad hoc for insertion into already-existing works. Drigo is also noted for his adaptations of already-existing scores, such as his 1895 edition of Pyotr Ilyich Tchaikovsky's score for Swan Lake. Many pieces set to the music of Drigo are still performed today, and are considered cornerstones of the classical ballet repertory.
