Are both A Midsummer Night's Dream and La sonnambula operas?
La sonnambula La sonnambula ("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.
