Who wrote the music and lyrics for “Let It Go” in Frozen?

Kristen Anderson-Lopez and Robert Lopez wrote the music and lyrics for “Let It Go” in Frozen.

The married songwriting team created the song for Elsa’s pivotal departure from Arendelle. Their work combines a theatrical power ballad with lyrics about self-acceptance, making the number function as both a memorable song and a major plot event.

The Lopezes had already written for stage and screen before Frozen. Robert Lopez was known for co-creating the musicals Avenue Q and The Book of Mormon, while Kristen Anderson-Lopez worked on musical theater and film projects. Their Frozen work earned them the Academy Award for Best Original Song.

They returned as songwriters for Frozen II, contributing songs including “Into the Unknown,” “Show Yourself,” and “Lost in the Woods.” “Let It Go” remains their best-known collaboration with Disney.
