From what can be heard in the soundtrack, there are six new themes, representing "Fawkes the Phoenix", "The Chamber of Secrets", "Gilderoy Lockhart", "Dobby the House Elf", "The Spiders", and "Moaning Myrtle".
Upon its release, the soundtrack was available in one of five different collectible covers. Each cover featured a different character or characters packaged above the main cover featuring Harry, Ron, and Hermione.
Though it does not appear on the soundtrack album, the Quidditch scene features a passage of a cue from "Zam the Assassin and the Chase Through Coruscant", a track from the soundtrack to Star Wars Episode II: Attack of the Clones, another score by Williams released earlier in the same year. It is not known why the cue was used; however, it is likely due to time constraints.
