Are both Der Freischütz and Der Barbier von Bagdad operas?
Der Barbier von Bagdad: Der Barbier von Bagdad ("The Barber of Baghdad") is a comic opera in two acts by Peter Cornelius to a German libretto by the composer, based on "The Tale of the Tailor" and "The Barber’s Stories of his Six Brothers" in "One Thousand and One Nights".
