It was a simple decision to borrow themes from Grieg's music to inspire the little songs I was to write for this story. I decided to borrow the sneaky rhythmic motives from "In the Hall of the Mountain King" to inspire the Troll's song. And I decided to quote a section from the etherial opening theme of "In a Morning Mood" to create the happy freedom song for the Billy Goats. Both of these orchestral pieces are from Edvard Grieg's "Peer Gynt Suite." I also tried to keep true to the orchestration flavors as much as possible.
