Where the first soundtrack saw a slow progression of the thematic development as the journey through Narnia unfolded, the structure of the Prince Caspian story does not allow for that. The film is paced differently than the book, omitting the tale of Caspian's upbringing and starting with his escape from Miraz rather than with the Pevensie's return at the train station. Unfortunately, the soundtrack album does not stand up to The Lion, The Witch, and The Wardrobe. Overall, the score is, as expected, very good. Gregson-Williams also wrote new themes for the Prince Caspian and Reepicheep characters, as well as the new villains, the Telmarines. The Heroic theme becomes the most prominent motif in the film while the Children's theme takes a backseat.
The Narnia theme returns along with a host of others. Harry Gregson-Williams' score follows this progression and continues the thematic development he began in the first film. The film is darker, the characters are put in more dangerous situations, and the primary components are battles rather than journeys, as in The Lion, The Witch, and The Wardrobe. With The Chronicle of Narnia: Prince Caspian moves the Narnia series further toward the Action/Adventure genre and slightly away from the children's film genre.
