Jon Burlingame editorAs the Marvel Cinematic Universe has expanded into television, its musical reach has also grown, embracing diversity both in terms of its composers and the music they make.English composer Natalie Holt (pictured above) brought unexpected sonorities to “Loki”; Cairo-based Hesham Nazih added specific Egyptian sounds to “Moon Knight”; and American composer Laura Karpman employed a traditional orchestra and choir on the animated “What If…?”“Loki is sort of a likable baddie,” says Holt, “a grand, Machiavellian, Shakespearean character, so I wanted some kind of gravitas, classical weight, to his theme.”Yet, in last summer’s six-part series, the Norse god of mischief (Tom Hiddleston) is also playing with time, which suggested more unusual sounds: the wailing of a theremin and its equally eerie French cousin, the ondes Martenot. “I’d been listening to [Lithuanian theremin virtuoso] Clara Rockmore and [BBC Radiophonic Workshop pioneer] Delia Derbyshire,” Holt explains.
