Britten, Benjamin, 1913-1976. Turn of the screw

The Turn of the Screw, Op. 54, is a 20th-century English chamber opera composed by Benjamin Britten, with a libretto by Myfanwy Piper, based on the 1898 novella The Turn of the Screw by Henry James. It concerns a young, inexperienced governess sent to a country house to care for two children, who she is gradually convinced have been corrupted by the ghosts of a previous manservant and governess. The drama grows increasingly tense, with a tragic outcome. It has been described by The Guardian as one of the most dramatically appealing of Britten's operas, and by music professor Peter Evans as "Britten's most intricately organized opera". It is in two acts of eight scenes each, with a prologue that ends with the introduction of a twelve-note 'Screw' theme. Each scene is preceded by a variation on that theme. Several other related leitmotifs occur through the opera. Typically of Britten, the music mixes tonality and atonality.
