Who composed the songs for the Frozen films?

Robert Lopez and Kristen Anderson-Lopez composed the songs for the Frozen films.

The husband-and-wife songwriting team wrote the original songs for Frozen, including “Let It Go,” “Do You Want to Build a Snowman?,” and “In Summer.” They also wrote the songs for Frozen 2 and for related projects such as Frozen Fever, whose featured number is “Making Today a Perfect Day.”

Their work helped define Frozen as a musical franchise. For the first film, the pair wrote 25 songs during development, with eight included in the final movie. The soundtrack also contains alternate and reprise performances, including the end-credit version of “Let It Go.”

A frequent source of confusion is the difference between songs and the orchestral score. Christophe Beck composed the score for Frozen and Frozen Fever, while the Lopezes wrote the songs. “Let It Go” won the Academy Award for Best Original Song, and its success helped Robert Lopez become an EGOT winner after his earlier Emmy, Grammy, and Tony awards.
