Filled with waltzes, marches and polkas, the music of Die Fledermaus is thoroughly high-spirited. Act I is set in the drawing room of Gabriel Eisenstein and his wife, Rosalinda. There’s a former lover (an Italian opera singer) and a (scheming) maid for her, a lawyer (Dr. Blind) and a Jail Warden for him, and for them both is Gabriel’s old friend, Dr. Faulke, who has planned an elaborate joke on Gabriel for that night as revenge for one Gabriel played on him a few years earlier. Act II is set entirely in a ballroom at a fancy party thrown by a rich Russian prince, so there’s lots of waltzing, and the entire cast sings of the virtues of champagne! Act III is set in a jail where all of the loose ends of the narrative get tied up to everyone’s satisfaction -- eventually.
