Crossover is a term applied to musical works or performers who appeal to different types of audience. This can be seen, for example, when a song appears on two or more of the record charts which track differing musical styles or genres. If the second chart combines genres, such as a "Hot 100" list, the work is not a crossover.

Turandot is an opera in three acts by Giacomo Puccini to a libretto in Italian by Giuseppe Adami and Renato Simoni. Puccini left the opera unfinished at the time of his death in 1924; it premiered in 1926 after the music was posthumously completed by Franco Alfano.
