David Arnold's principal musical focus is melody. Whether he's reworking the James Bond theme or scoring Sherlock, his TV and movie soundtracks are notable for their strikingly lyrical refrains. These not only heighten the emotional drama but also linger in the mind, giving on-screen events a haunting quality. He brings in unorthodox instruments from non-orchestral disciplines, too, like a hammered dulcimer, jazz trumpet or Fender Rhodes piano, to ensure his scores match the unique flavour of the action they support.
