There is a moment, near the end of Puccini's final opera, when the music simply stops. Not the recording, not the performance. At the world premiere at La Scala in 1926, the conductor Arturo Toscanini put down his baton mid-act, turned to the audience, and said, by most accounts, "Here the Maestro laid down his pen." Then he walked off. Puccini had died before finishing the opera, and Toscanini refused, that first night, to play the ending another man had completed. Somewhere in the third act sits the aria that would outlive them all: Nessun dorma.
What you're listening to
Turandot is a fairy-tale set in a mythical Peking. A cold princess has vowed to marry no man unless he solves three riddles; every suitor who fails is executed. An unknown prince, Calaf, solves them anyway, then offers her a way out: if she can learn his name by dawn, he will die. The princess decrees that no one in the city shall sleep until the name is found. Nessun dorma, "none shall sleep," is Calaf's answer to that decree, sung alone in the night. He knows something she does not. He is going to win. The aria climbs to a final word, "Vincerò" ("I will win"), on a high, ringing B that has become the single most recognizable note in opera.
What makes it special
It is three minutes of pure confidence. Most great arias are laments. This one is the opposite: a man completely certain, in the dark, that dawn will be his. The melody rises and rises and simply refuses to come down, and the effect on a listener is almost physical.
It was built for one held note. Everything in the aria is engineering toward that final "Vincerò." Singers spend careers preparing for it; audiences wait for it; the whole three minutes is a runway for one takeoff. When a tenor lands it cleanly, arenas erupt.
A composer's death is written into it. Puccini worked on Turandot for years while dying of throat cancer, and stopped a few scenes after this aria. The opera was finished from his sketches by Franco Alfano. So the most soaring, victorious music Puccini ever wrote sits just before the point where his own hand fell silent. Triumph and unfinishedness, in the same act.
The story behind it
For most of the twentieth century, Nessun dorma was known and loved inside the opera world and largely unknown outside it. That changed because of football. In 1990, the BBC chose Luciano Pavarotti's recording as the theme for its coverage of the World Cup in Italy, and days before the final, Pavarotti, Plácido Domingo, and José Carreras sang together in Rome as the Three Tenors, closing with this aria. A recording of that concert became the best-selling classical album in history. Overnight, a three-minute piece from a 1926 opera was a global pop anthem, sung in stadiums, hummed by people who had never seen an opera and never would.
Pavarotti made it his signature for the rest of his life, and sang it at his last public performance, at the 2006 Winter Olympics in Turin, already ill; it was later revealed the audio was pre-recorded because he was too weak to risk the high B live. He died the following year. His funeral, in Modena, ended with a recording of Pavarotti himself singing Nessun dorma, his own voice saying goodbye.
One detail most people miss
Listen to the very end, the last "Vincerò." In the opera, Calaf is wrong to be so sure, and right at the same time: the princess does thaw, love does win, but only after more death. Yet stripped out of the plot and sung in a stadium, the aria means something simpler and truer than the story around it. It is what hope sounds like when a person decides, against all evidence, in the middle of the night, that the morning belongs to them.
