Expanding on their seven songs from the film, songwriters Kristen Anderson-Lopez and Robert Lopez wrote an additional 12 songs for the stage adaptation. Many of these songs focus on deepening the characters of Anna, Elsa, Hans and Kristoff and their relationships with each other.
In addition to the contemporary ‘West End Musical’-styled sounds of the score, the music draws inspiration from the story’s setting. The Hidden Folk perform a joik, which is a traditional Saami form of song. Joiking is one of the longest living music traditions in Europe, dating back centuries. The music is often interpreted not to be about a person or place, but instead invoking that person or place. It does not need to include words, but can weave a narrative through words, melody, rhythm, expressions or gestures. Examples of joik in FROZEN are the “Vuelie” theme heard at the very beginning of the show, and the call that both Queen Iduna and Kristoff make to summon the Hidden Folk.
