Are both the Louise and the La clemenza di Tito operas?
Louise (opera) Louise is an opera ("roman musical" ) in four acts by Gustave Charpentier to an original French libretto by the composer, with some contributions by Saint-Pol-Roux, a symbolist poet and inspiration of the surrealists.
Semirâma Semirâma is an opera in three acts by Ottorino Respighi to a libretto by Alessandro Cerè based on Voltaire's 1748 play "Sémiramis", the same subject used for Rossini's Semiramide. "Semirâma" premiered on 20 November 1910 at the Teatro Comunale in Bologna. The première obtained a great success, with several calls for the composer and the singers.
