Which had more acts/ scenes, The Snow Maiden or Sadko?
Sadko (opera) Sadko (Russian: Садко , the name of the main character) is an opera in seven scenes by Nikolai Rimsky-Korsakov. The libretto was written by the composer, with assistance from Vladimir Belsky, Vladimir Stasov, and others. Rimsky-Korsakov was first inspired by the Bylina of Sadko in 1867, when he completed a tone poem on the subject, his Op. 5. After finishing his second revision of this work in 1891, he decided to turn it into a dramatic work.
Lady Macbeth of the Mtsensk District (opera) Lady Macbeth of the Mtsensk District (Russian: "Леди Макбет Мценского уезда" , or "Ledi Makbet Mtsenskogo uyezda") is an opera in four acts and nine scenes by Dmitri Shostakovich, his Opus 29. The libretto, jointly written by Alexander Preys and the composer, is based on the novel of the same name by Nikolai Leskov. (The opera is incorrectly named "Lady Macbeth of Mtsensk" on several commercial CD and DVD recordings.)
