It is a piece of orchestral music composed by Edvard Grieg in 1875.
In this piece of music, the adventures of the anti-hero, Peer Gynt, are related, including the episode in which he steals a bride at her wedding. The angry guests chase him, and Peer falls, hitting his head on a rock. He wakes up in a mountain surrounded by trolls. The music of "In the Hall of the Mountain King" represents the angry trolls taunting Peer and gets louder each time the theme repeats. The music ends with Peer escaping from the mountain.
