Turandot (Italian pronunciation: [turan ˈdɔt]) is an opera in three acts by Giacomo Puccini, set to a libretto in Italian by Giuseppe Adami and Renato Simoni. Though Puccini's first interest in the subject was based on his reading of Friedrich Schiller's adaptation of the play, his work is most nearly based on the earlier text Turandot by Carlo Gozzi. Turandot was unfinished at the time of Puccini's death and was later completed by Franco Alfano. The first performance was held at the Teatro alla Scala in Milan on April 25, 1926 and conducted by Arturo Toscanini. This performance included only Puccini's music and not Alfano's additions. The first performance of the opera as completed by Alfano was the following night.
