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.
Sly (opera) Sly, ovvero La leggenda del dormiente risvegliato (English: "Sly, or The Legend of the Sleeper Awoken") is an opera in three acts by Ermanno Wolf-Ferrari to an Italian libretto by Giovacchino Forzano, based on the Induction (the Prologue) to William Shakespeare's "The Taming of the Shrew" (the German version of libretto, "Sly, oder Die Legende vom wiedererweckten Schläfer", was translated by ). Unlike most of Wolf-Ferrari's other operas, this is a tragedy.
