Of all the characters in “The Assassination of Gianni Versace: American Crime Story,” Donatella Versace doesn’t have the most screentime. But like Penelope Cruz’s distinct portrayal, the score of the FX series lets her linger throughout the story.

“Versace” composer Mac Quayle has effectively used digital scores in other TV series, most notably in “Mr. Robot.” For one of the central Donatella compositions, Quayle makes a haunting mix of electronic hums, distant keys and a surprising crescendo to some haunting strings. It’s a blending of digital and tactile that mirrors the way the rest of this season’s unconventional timeline blends past and future.

“After I had written the score to the first episode I realized the music was essentially Giorgio Moroder scoring ‘Silence of the Lambs’ in an Italian Villa,” Quayle told IndieWire. “From the moment we meet Donatella Versace she is grieving the loss of her brother, and so I wanted her theme to embody that deep sadness.”

For a series working backwards from a tragedy through two men’s individual backstories, the “Versace” score has helped root the emotion in whenever the show’s “present” happens to be. Sometimes it’s in a dreamlike prelude to a nightmare, other times it’s in a sister mourning the loss of a brother with whom she had a contentious, complicated relationship.

The full soundtrack album for “The Assassination of Gianni Versace: American Crime Story” will be available on Friday, March 16 in advance of next Wednesday’s finale.
