Edvard Grieg is best known for the incidental music he wrote for Henrik Ibsen’s play, Peer Gynt. Incidental music provides background or atmosphere for the action in a play. Peer Gynt is a tale about one man’s epic journey to the four corners of the globe. Grieg’s “In the Hall of the Mountain King” describes Peer Gynt’s adventure in the underground Kingdom of the Trolls. Can you hear the trolls creeping up on Peer? They are coming faster and faster!
