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.
Achille et Polyxène Achille et Polyxène ("Achilles and Polyxena") is a tragédie lyrique containing a prologue and five acts based on Virgil's "Aeneid" with a French libretto by Jean Galbert de Campistron. The opera's overture and first act were composed by Jean-Baptiste Lully, who died from a conducting injury before he could complete the score. The prologue and the remaining acts are the work of his pupil Pascal Collasse who finished the work, eight months after Lully's death on March 22, 1687. The opera was first performed on November 7, 1687, by the Paris Opera at the Théâtre du Palais-Royal in Paris.
