Shore used his themes in defiance to the common practices of film music (and even some theatre works) by strictly applying them for narrative purposes, never resorting to using them purely to suggest mood, although several intriguing instances still exist in his work: he replaced the Realm of Gondor theme used for the passage of the Argonath with a statement of The History of the One Ring theme, the main theme of the trilogy, to denote the film coming to a close; and he used the so-called Ringwraith theme (which in fact applies more broadly to all the servants of Sauron) to the Orc armies of the prologue. Otherwise, the only instance of music outside of the narrative is done by means of tracked music, featuring the Moria motif being applied by the filmmakers to the Warg attack in the Two Towers instead of Shore's original intention.
