La sonnambula

La sonnambula (Italian pronunciation: [la sonˈnambula]; The Sleepwalker) is an opera semiseria in two acts, with music in the bel canto tradition by Vincenzo Bellini set to an Italian libretto by Felice Romani, based on a scenario for a ballet-pantomime written by Eugène Scribe and choreographed by Jean-Pierre Aumer called La somnambule, ou L'arrivée d'un nouveau seigneur. The ballet had premiered in Paris in September 1827 at the height of a fashion for stage works incorporating somnambulism. The role of Amina was originally written for the soprano sfogato Giuditta Pasta, but during Bellini's lifetime another soprano sfogato, Maria Malibran, was a notable exponent of the role. The first performance took place at the Teatro Carcano in Milan on 6 March 1831.
