Let It Go

Idina Menzel's signature song from Frozen, as arranged for solo piano, strips the power-ballad production down to its melodic and harmonic essentials. Lang Lang's interpretation reveals that "Let It Go" is, underneath the orchestral production and the belted high notes, a carefully constructed piece of musical theater writing — the harmonic movement doing real emotional work, the melody structured to climax at precisely the moment the character achieves psychological liberation. Without Menzel's voice, the piano must carry the sense of release that the original builds through vocal power, and Lang Lang achieves this through dynamic contrast and registral ascent, the right hand climbing into the upper octaves at the song's emotional apex. The song's cultural ubiquity — it became inescapable after Frozen's 2013 release — makes it difficult to hear freshly, but the piano arrangement offers a slightly cooled, slightly formal version of the melody that distances it productively from the sing-along associations. The middle section, where the original's tempo drops and Elsa speaks to herself in newly confident terms, translates to piano as a moment of stillness before the final release. This is feel-good music that knows exactly what it is doing structurally, and Lang Lang plays it with the respect that workmanlike excellence in any field deserves — not condescending to it, not elevating it beyond its nature, simply executing it at the highest level available.
