Number 39 in the Big Book of Classical Music is a classic. That’s why it’s in the book.
In The Hall of the Mountain King, by Edvard Grieg (1843-1907) is a piece of orchestral music composed in 1875 as incidental music for the sixth scene of act 2 in Henrik Ibsen’s 1867 play Peer Gynt.
It was originally part of Opus 23 but was later extracted as the final piece of Peer Gynt, Suite No. 1, Op. 46. Its easily recognizable theme has helped it attain iconic status in popular culture, where it has been arranged by many artists, including me!
