Ludwig van Beethoven’s only opera, the masterpiece “Fidelio,” presents a timeless narrative of love and political courage. The plot centers on the heroic Leonore, who disguises herself as the prison guard Fidelio to secure her husband’s release from confinement. Among the work’s most celebrated moments are the haunting prisoners’ chorus and the demanding arias for Leonore and Florestan. The grand finale serves as an exaltation of love, virtue, and liberty. “Fidelio” received its premiere in Vienna in 1814.
