La Sonnambula

For George Balanchine's 1946 ballet, see La Sonnambula (ballet).
La sonnambula (The Sleepwalker) is an opera semiseria in two acts, music by Vincenzo Bellini to an Italian libretto by Felice Romani, based on a ballet-pantomime by Eugène Scribe.
The first performance took place at the Teatro Carcano, Milan on March 6, 1831.
With its pastoral setting and story, La sonnambula was an immediate success and is still regularly performed. The title role of Amina (the titular sleepwalker) with its high tessitura is renowned for its difficulty, requiring a complete command of trills and florid technique.

Synopsis
Act 1
Scene 1: A village, a mill in the background
Lisa, the proprietress of the inn, is consumed with jealousy as the betrothal procession of Amina and Elvino, who had once been betrothed to her, approaches.

Amina thanks her friends for their kind wishes and particularly her foster-mother Teresa, owner of the mill, who had adopted her as an orphan. She thanks Alessio, who had composed the wedding song and organised the celebrations, wishing him well in his courtship of Lisa, who continues to reject his advances.Elvino arrives, having stopped on his way at his mother's grave to ask her blessing on Amina. Lisa points out that it is getting late and he will not reach it before dark and offers him lodging at her inn.

The newcomer, who surprises the villagers by his familiarity with the locality, asks about the celebrations and admires Amina, who reminds him of a girl he had loved long ago. He admits to having once stayed in the castle, whose lord has been dead for four years.When Teresa explains that his son had vanished some years previously, the stranger assures them that he is alive and will return.
As darkness approaches the villagers warn him that it is time to be indoors to avoid the village phantom, but he is not superstitious and assures them that they will soon be free of the apparition. Elvino is jealous of the stranger's admiration of Amina; he is jealous even of the breezes that caress her, but he promises her he will reform.
Scene 2: A room in the inn


Jenny Lind in La Sonnambula.

Lisa tells the stranger that he has been recognised as Rodolfo, the long-lost son of the count, and warns him that the village is preparing a formal welcome.

She is flattered when he begins a flirtation with her, but runs out, dropping a handkerchief, when a sound is heard outside.
It is Amina, who enters the room, walking in her sleep. Rodolfo, realising that her nocturnal wanderings have given rise to the story of the village phantom, is about to take advantage of her helpless state, but is struck by her obvious innocence and refrains.She falls asleep on the sofa and he goes outside as the villagers are heard advancing on the inn to welcome their new lord. Only Teresa believes in her innocence.
Act 2
Scene 1: A wood
On their way to ask the count to attest to Amina's innocence, the villagers meet Amina and Teresa, on a similar mission.

Elvino is not convinced and takes back the ring, though he is unable to tear her image from his heart.
Scene 2: The village, as in Act I
Elvino has decided to marry Lisa. They are about to go to the church when Rodolfo tries to explain that Amina is innocent because she had not come to his room awake - she is a somnambulist, a sleepwalker, but Elvino refuses to believe him.
Teresa begs the villagers to be quiet, because Amina has at last fallen into an exhausted sleep.Learning of the impending marriage, she confronts Lisa, who says that she has never been found alone in a man's room. Rodolfo warns that to wake her would be fatal, so all watch as she relives her betrothal and her grief at Elvino's rejection.
