What is Lacrimosa?

The Mozart song Lacrimosa is a symbol of mourning the Belsey marriage. The family sees a performance of the song early in the novel, and the haunting melody resonates deeply with Kiki. Howard, however, is against the religious themes of the music. At the end of the novel, Howard plays the song loudly in his car. He is mourning his marriage, but also finding celebration in release from his own rules.
