Are both A Midsummer Night's Dream and La sonnambula operas?
A Midsummer Night's Dream (opera) A Midsummer Night's Dream, Op. 64, is an opera with music by Benjamin Britten and set to a libretto adapted by the composer and Peter Pears from William Shakespeare's play, "A Midsummer Night's Dream". It was premiered on 11 June 1960 at the Aldeburgh Festival, conducted by the composer and with set and costume designs by Carl Toms. Stylistically, the work is typical of Britten, with a highly individual sound-world – not strikingly dissonant or atonal, but replete with subtly atmospheric harmonies and tone painting. The role of Oberon was composed for the countertenor Alfred Deller. Atypically for Britten, the opera did not include a leading role for his partner Pears, who instead was given the comic drag role of Flute/Thisbe.
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.
