<P> Although "Nessun dorma" has long been a staple of operatic recitals, Luciano Pavarotti popularized the piece beyond the opera world in the 1990s following his performance of it for the 1990 World Cup . Both Pavarotti and Plácido Domingo released singles of the aria that topped charts in the United Kingdom, and it appeared on the best selling classical album of all time, The Three Tenors in Concert . Since that time, many crossover artists have performed and recorded it . The aria has been sung often in movies and on television . </P> <P> In the act before this aria, Calaf has correctly answered the three riddles put to all of Princess Turandot's prospective suitors . Nonetheless, she recoils at the thought of marriage to him . Calaf offers her another chance by challenging her to guess his name by dawn . As he kneels before her, the "Nessun dorma" theme makes a first appearance, to his words, "Il mio nome non sai!" (My name you do not know!). She can execute him if she correctly guesses his name; but if she does not, she must marry him . The cruel and emotionally cold princess then decrees that none of her subjects shall sleep that night until his name is discovered . If they fail, all will be killed . </P> <P> As the final act opens, it is now night . Calaf is alone in the moonlit palace gardens . In the distance, he hears Turandot's heralds proclaiming her command . His aria begins with an echo of their cry and a reflection on Princess Turandot: </P> <Dl> <Dd> <Table> <Tr> <Td> <P> Nessun dorma! Nessun dorma! Tu pure, o Principessa, nella tua fredda stanza, guardi le stelle che tremano d'amore, e di speranza! </P> </Td> <Td> <P> None shall sleep! None shall sleep! Not even you, oh Princess, in your cold bedroom, watching the stars that tremble with love and with hope! </P> </Td> </Tr> <Tr> <Td> <P> Ma il mio mistero è chiuso in me; il nome mio nessun saprà! No, No! Sulla tua bocca lo dirò quando la luce splenderà! </P> </Td> <Td> <P> But my secret is hidden within me; no one will know my name! No, no! On your mouth I will say it when the light shines! </P> </Td> </Tr> <Tr> <Td> <P> Ed il mio bacio scioglierà il silenzio che ti fa mia! </P> </Td> <Td> <P> And my kiss will dissolve the silence that makes you mine! </P> </Td> </Tr> </Table> </Dd> </Dl>
