To maintain the mood, minor keys are used throughout. To correlate with the movie, the percussion comes from noises in the actual film. A flute enters in, creating a cheerful line. When they sing minor harmonies, I can feel the tears streak down my cheeks. That's how powerful the chord structure of this song is.
Melancholy strings end the song.
There's no need to skip tracks on this album. They all run together smoothly to create a fully satisfying mix of elation and melancholy. The use of horns, combined with drum machine effects, create an assured pulse that invokes looking to the future. Her refusal to compromise her artistic vision allows her to create masterful works. But she is always original.
