You don’t have to know Beethoven to find yourself thoroughly absorbed by the theatricality with which playwright Moises Kaufman has tied a historic event. The legendary mystery surrounding one of Beethoven’s compositions links to a drama about a fatally ill Beethoven scholar, her relationship with her daughter, and the daughter’s burgeoning romance. Drama, memory, and music combine to transport audiences from present-day New York to 19th century Austria in this American play.
