The Threepenny Opera The Threepenny Opera (Die Dreigroschenoper ) is a "play with music" by Bertolt Brecht and Elisabeth Hauptmann, adapted from John Gay's 18th-century English ballad opera, "The Beggar's Opera", with music by Kurt Weill and insertion ballads by François Villon and Rudyard Kipling. Although Hauptmann produced 80 to 90 percent of the text, Brecht suppressed this and assumed sole credit, and is usually listed as sole author in printed versions.
Der Zwerg Der Zwerg ("The Dwarf"), Op. 17, is an opera in one act by Austrian composer Alexander von Zemlinsky to a libretto by Georg Klaren, freely adapted from the short story "The Birthday of the Infanta" by Oscar Wilde.
