Are Béatrice et Bénédict and Les pêcheurs de perles both operas?
Béatrice et Bénédict Béatrice et Bénédict ("Beatrice and Benedick") is an opéra comique in two acts by Hector Berlioz. Berlioz wrote the French libretto himself, based closely on Shakespeare's "Much Ado About Nothing".
Bluebeard (ballet) Barbe-bleue (en. "Bluebeard") (ru. «Синяя борода», "Sinjaja boroda") is a "ballet-féerie" in three acts and seven scenes, originally choreographed by Marius Petipa to the music of Pyotr Schenk. The libretto was created by the author and dramatist Countess Lydia Pashkova from the fairy tale "Bluebeard" by Charles Perrault. The ballet was first presented by the Imperial Ballet on December 20 [O.S. December 8] 1896 at the Imperial Mariinsky Theatre in St. Petersburg, Russia, the first performance being a benefit in honor of Marius Petipa's fiftieth anniversary in service to the St. Petersburg Imperial Theatres.
