what kind of music is in Vanessa and King Priam?
Vanessa (opera) Vanessa is an American opera in three (originally four) acts by Samuel Barber, opus 32, with an original English libretto by Gian-Carlo Menotti. It was composed in 1956–1957 and was first performed at the Metropolitan Opera in New York City on January 15, 1958 under the baton of Dimitri Mitropoulos in a production designed by Cecil Beaton and directed by Menotti. Barber revised the opera in 1964, reducing the four acts to the three-act version most commonly performed today.
Aleatoric music Aleatoric music (also aleatory music or chance music; from the Latin word "alea", meaning "dice") is music in which some element of the composition is left to chance, and/or some primary element of a composed work's realization is left to the determination of its performer(s). The term is most often associated with procedures in which the chance element involves a relatively limited number of possibilities.
