Other songs include "Frozen Heart," "Do You Want to Build a Snowman?" "Love Is an Open Door," "Reindeer(s) Are Better Than People" and "Fixer Upper."An Inspired ScoreComposer Christophe Beck, whose diverse talents are evident by a resume that includes the Oscar®-winning "Paperman" and the "Hangover" trilogy, provided an epic score for "Frozen." "The people at Disney really value music," said Beck. "And in animation, versus live action, the music is really integral to the storytelling—it does some of the heavy lifting when it comes to communicating the emotion." Beck paid homage to the Norway-inspired setting, referencing regional instruments such as the haunting bukkehorn and vocal techniques like kulning, which is a traditional shepherd's herding call. "With 'Frozen,'" he said, "we had the setting to draw from—these incredible icy snowy vistas, which are very evocative. The region provided us with lots of really cool and interesting sound to explore that I'd never heard—I don't think many people outside of the region have either." Filmmakers recruited a Norwegian linguist to help with the lyrics for an Old Norse song written for Elsa's coronation. And the team even travelled to Norway to record the all-female choir Cantus for a piece inspired by traditional Norwegian music. The score, which was recorded by a full 80-piece orchestra, features 32 vocalists—including native Norwegian Christine Hals, whose rural upbringing inspired her kulning skills. Beck worked with Lopez and Anderson-Lopez on some of the songs' arrangements and in incorporating their melodies in the score, often doing so in a unique, but recognizable context. According to Buck, the collaboration went even further for "Do You Want to Build a Snowman?" "The song reflects Anna's side of the story—which is sung by Kristen Bell, Agatha Lee Monn and Katie Lopez as Anna, and written by Bobby and Kristen—and Elsa's side, which is represented by Christophe's score. It is all woven together beautifully," said the director. "And the melody returns at the end of the film in a really grand and moving way." "Our goal," added Beck, "was to create a cohesive musical journey from beginning to end."
