Are Maria Stuarda and Salome both operas?
Maria Stuarda Maria Stuarda (Mary Stuart) is a tragic opera ("tragedia lirica"), in two acts, by Gaetano Donizetti, to a libretto by Giuseppe Bardari, based on Andrea Maffei's translation of Friedrich Schiller's 1800 play "Maria Stuart".
Un dì, felice, eterea "Un dì, felice, eterea" ("One day, happy and ethereal") is a duet from the first act of Giuseppe Verdi's opera "La Traviata". It is sung by the male and female protagonists of the opera, Alfredo (a tenor) and Violetta (a soprano). The main melody of the duet, which is very famous in its own right, is also an important musical theme throughout the opera. It is also notable for being one of the songs heard in the film "Pretty Woman" and also at the end of "The Bitter Tears of Petra von Kant".
