Development
Gregson-Williams looked back to the advantage of the 14th century setting to guide the score and the narrative that builds to the judicial duel Jean de Carrouges (Matt Damon) and Jacques Le Gris (Adam Driver) after Marguerite (Jodie Comer) accuses the latter of rape. Scott had suggested him not to underscore the battle sequences, going with the "sound effects of horses snorting and swords clashing" and provide intro and outro music for those sequences.
In an unusual way of composing the film's music, Gregson-Williams tasked to take note of the last page of the script, which had a sequence where Marguerite singing to her young child (ultimately deleted from the film). Taking inspiration from medieval composer Theobald, Count of Champagne, he provided a melodic theme that eventually became Marguerite's theme. For de Carrouges, he wanted the thematic material "to start out quiet, stout and heroic and maybe warlike drums, but quite expected" and for Le Gris, he wanted an unsettling tone, for which he sought singer Iestyn Davies to provide countertenor vocals. He further integrated with moody orchestral textures and gentle synthesizers for the "dark and imposing music" to surround Jacques [Le Gris] in the third act.
He considered medieval instruments to bring historical authenticity to the score, but as he felt that it would restrict them to move the story forward, especially in the Rashomon-style narrative between the three characters, he used a consort of viols that had "an edgy sound and bring to mind early music" despite not being developed during that period, and used lutes and gossamers, being layered over a "decent-sized orchestra".
