Russian opera (Russian: Ру́сская о́пера) is the art of opera in Russia. Operas by composers of Russian origin, written or staged outside of Russia, also belong to this category, as well as the operas of foreign composers written or intended for the Russian scene. These are not only Russian-language operas. There are examples of Russian operas written in French, English, Italian, Latin, Ancient Greek, Japanese, or the multitude of languages of the nationalities that were part of the Empire and the Soviet Union.Russian opera includes the works of such composers as Glinka, Mussorgsky, Borodin, Tchaikovsky, Rimsky-Korsakov, Stravinsky, Prokofiev and Shostakovich.Searching for its typical and characteristic features, Russian opera (and Russian music as a whole), has often been under strong foreign influence. Italian, French, and German operas have served as examples, even when composers sought to introduce special, national elements into their work. This dualism, to a greater or lesser degree, has persisted throughout the whole history of Russian opera.
