Benjamin Wallfisch was the composer for Shazam. The film marks the third collaboration between Wallfisch and director David F. Sandberg having scored his debut film Lights Out and Annabelle: Creation.[2] For the score of Shazam, Sandberg and Wallfisch leaned into the territory of old-school fun adventure movies, taking inspiration from the scores of the 1970s and 1980s, specifically that of Superman by John Williams and Back to the Future by Alan Silvestri. Sandberg noted "that many modern scores have moved away from such traditional music" and as such made the score a fitting homage to the Golden Age of Hollywood.[3]
Wallfisch noted that the film's story had that "kind of tenderness at the heart of the story" and a sense of "optimism for the future". From there, he crafted several themes – Sivana's theme, the Wizard theme, the music for the Seven Deadly Sins, the family theme and Shazam's themes which comprises a Hero theme and a Transformation theme and worked around creating a melodic soundscape, balancing between the comedy and adventure aspects. For the film's villain, Dr. Sivana, Wallfisch opted for a minimalist approach utilising only low male choir, extended bass woodwinds and brass.[4][5][6]
The score was recorded at AIR Lyndhurst Studios in Hampstead, London with a 140-piece Chamber Orchestra of London and was conducted by Wallfisch and Chris Egan.[7]
