Peer Gynt is a five-act play in verse by the Norwegian dramatist Henrik Ibsen, loosely based on the fairy tale Per Gynt. Written in the Dano-Norwegian language, it is the most widely performed Norwegian play. Peer Gynt has also been described as the story of a life based on procrastination and avoidance. Peer Gynt was first performed in Christiania (now Oslo) on 24 February 1876, with original music composed by Edvard Grieg, which includes some of today's most recognized classical pieces, In the Hall of the Mountain King and Morning Mood.
