Contents
Turandot sets a cold princess and a deadly riddle test against a slave girl’s loyalty, and it is a score that another composer had to finish. Singers meet it as a dramatic soprano test, a tenor showpiece and a long evening that rewards a clear plot map. This page gives the facts to check first, one of the guides in the operas section.
At a glance
Giacomo Puccini, an Italian opera composer, lived from 1858 to 19245. He began working on Turandot in March 1920, after meeting the librettists Giuseppe Adami and Renato Simoni1. Puccini died in 1924 and the opera was left unfinished1. Franco Alfano completed the music, and it premiered on 25 April 1926, almost a year and a half after Puccini’s death1. The libretto is Italian and is based on Carlo Gozzi’s play Turandot1.
Gozzi’s play dates from 1762, and Friedrich Schiller adapted it into another play in 18011. Turandot lasts approximately 2 hours 55 minutes, including two intervals4. The setting is Peking, in legendary times3.

Synopsis
Act 1
Anyone who stands trial and fails will be executed3. The Prince of Persia has just failed to answer the riddles and is sentenced to be beheaded at moonrise2. A young man hears Liù’s cry and recognizes that the old man is his long-lost father, Timur, the deposed king of Tartary1. The young Prince of Tartary is overjoyed at seeing Timur alive, but urges Timur not to speak his name1. Timur tells his son that, of all his servants, only Liù has remained faithful to him1. Calaf learns that Timur owes his life to a slave girl, Liù, who accompanies him3.
Calaf attempts the riddles against the warnings of his father Timur, Liù, who is secretly in love with him, and the ministers Ping, Pang and Pong2. Ping, Pang and Pong try to stop him with “Fermo, che fai?”1. Liù implores him to leave with her and Timur, “Signore, ascolta”4. Calaf tries to console her with “Non piangere, Liù” but remains determined4.
Act 2
In order to win her hand, a suitor must solve three riddles, with a wrong answer resulting in his execution1. Turandot enters and explains in “In questa reggia” that her ancestress, Princess Lo-u-Ling, reigned over her kingdom1. The Prince correctly answers the first riddle: Speranza, hope1. Calaf passes the test, but Turandot refuses to marry him1.
Act 3
Timur and Liù are dragged in, suspected of knowing Calaf’s name4. Liù steps forward, claiming that she alone knows the prince’s name3. The slave girl refuses to yield under torture, and when asked what gives her such strength, she replies that it is love3. Liù seizes a dagger from a soldier’s belt and stabs herself1. Timur curses those who have brought about her death3.
The famous arias
| Aria | Role | Act | First line |
|---|---|---|---|
| Turandot’s opening aria | Turandot | Act 2 | In questa reggia1 |
| The ministers’ warning | Ping, Pang, Pong | Act 1 | Fermo, che fai?1 |
| Liù’s plea | Liù | Act 1 | Signore, ascolta!1 |
| Calaf consoles Liù | Calaf | Act 1 | Non piangere, Liù1 |
| Nessun dorma | Calaf | Act 3 | Nessun dorma1,4 |
In questa reggia is where Turandot explains her ancestress Lo-u-Ling in Act 21. Adami died in 1946 and Simoni in 1952, so their text has long been public domain6,7.
| Original | Our translation |
|---|---|
| Fermo, che fai?1 | Wait, what are you about? |

Background, premiere and reception
Puccini died of a heart attack, leaving the opera unfinished, and Turandot was posthumously completed by Franco Alfano4. After severe criticism by Ricordi and the conductor Arturo Toscanini, Alfano was forced to write a second, strictly censored version of the ending1. Puccini used Chinese melodies: Baron Edoardo Fassini-Camossi, the former Italian diplomat to China, gave him a music box that played four Chinese melodies1. Eight of the themes of Turandot appear to be based on traditional Chinese music and anthems1.
The premiere took place at the Teatro alla Scala on 25 April 1926 with Toscanini conducting1. The score gives the orchestra and chorus every opportunity to shine, and it includes the Act III anthem Nessun dorma3. Pavarotti sang Nessun dorma live with The Three Tenors in Los Angeles in 19943. For many years the government of the People’s Republic of China forbade performance of Turandot, and in the late 1990s they relented1.
Language and diction notes
The libretto is Italian, so the rules in Italian diction for singers apply throughout. The title of the best-known aria means None shall sleep, referring to the decree that no one in the city can sleep4. For translating a text like this line by line, see how to read a libretto.
For another Puccini heroine, try Tosca or Madama Butterfly.
