Do the operas Don Carlos and Pomone have the same number of acts?
Pomone (opera) Pomone ("Pomona") is a pastoral opera in a prologue and five acts by Robert Cambert with a libretto by Pierre Perrin. It has been described as "effectively the first French opera." It was first performed in Paris at the Jeu de Paume de la Bouteille theatre belonging to Cambert and Perrin's Académie d'Opéra on 3 March 1671. The production had ballets choreographed by Des Brosses and sets and machinery designed by Alexandre de Rieux, marquis de Sourdéac. The novelty of the work drew large audiences and the opera enjoyed 146 performances over the eight months of its run. The score of "Pomone" has only partially survived.
Ballo della Regina Ballo della Regina is a one-act ballet choreographed by George Balanchine to music by Giuseppe Verdi. It is a set of variations set to ballet music (titled "La Peregrina") that Verdi cut from Act 3 of the original 1867 version of his opera "Don Carlos". Its premiere performance was on 12 January 1978, by the New York City Ballet at New York State Theater in Lincoln Center.
