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.
Opéra féerie Opéra féerie (plural: "opéras féeries ") is a French genre of opera or opéra-ballet, often with elements of magic in their stories. Popular in the 18th century, from the time of Jean-Philippe Rameau onwards, the form reached its culmination with works such as "La belle au bois dormant" by Michele Carafa and "Cendrillon" by Nicolas Isouard at the beginning of the 19th century.
