Let It Go

Kristen Anderson-Lopez and Robert Lopez wrote Let It Go for the 2013 Disney film Frozen, and the song became one of the most-streamed tracks of the decade and won the Academy Award for Best Original Song. The Trinity Grade 3 arrangement (by Alastair Gavin) reduces the orchestral and vocal original to a piano solo that keeps the harmonic shape, the melodic hook and the song's clear emotional arc.

Technically the piece tests three skills: a clearly-shaped right-hand melody that ranges across more than a single hand position, a steady left-hand accompaniment that supports without weighing the line down, and the unfamiliar key of A♭ major (four flats). The melody has a clear verse-then-chorus shape and the dynamic plan should track that shape closely — the chorus is the piece's emotional centre and should arrive as a release.

Two pitfalls. First, students who know the song from the film often rush the verse to get to the chorus — the piece works much better with a measured verse and a real lift into the chorus. Second, the left-hand accompaniment can clatter under the melody; aim for a wrist-soft chordal touch that lets the right hand sing.

The film recording is commercial; for an editorial reference, examine the harmonic plan (an A♭ verse moving to D♭ at the chorus, with classic IV–V–vi–I voice-leading) as a study in pop harmonic architecture rather than copying any specific performance.
