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.
Veneen luominen Veneen luominen ("The Building of the Boat") is an unfinished composition by Jean Sibelius. The work was intended to be a grand opera, in the style of Richard Wagner's "Der Ring des Nibelungen", but was never completed, as Sibelius became disenchanted with Wagner's compositional techniques.
