The Queen of Spades, Op. 68 (Russian: Пиковая дама, Pikovaya dama, French: Pique Dame)[1] is an opera in 3 acts (7 scenes) by Pyotr Ilyich Tchaikovsky to a Russian libretto by the composer's brother Modest Tchaikovsky, based on a short story of the same name by Alexander Pushkin, but the plot was very changed. The premiere took place in 1890 in St. Petersburg (at the Mariinsky Theatre), Russia.[2]
