This change of mood and instrumentation is what enhances a story. By developing the music along with the story, the music becomes more complex by giving itself a narrative to follow.
Vaguely like Stravinsky’s The Firebird, we hear the piano and horns play an aggressive melody before the tension breaks with a hauntingly beautiful waltz. The music fits well with the original story of Lasko, Manny, Mo, and Jack who were Ratbeard’s poisoned crew mates, murdered by Ratbeard himself. Lasko wanted his crewmates to have their final wishes before being released to the afterlife and one of them wanted to return a locket to their lost love.
