 Howard Shore composed "The Valley of Imladris" - a diegetic piece for lute, lyre, wood flute and harp that is performed in Rivendell, a recapitulation of a piece of music introduced in the underscore previously as Elrond rides into Rivendell to meet the Dwarves.Shore also composed the horn-call at the end of Battle of the Five Armies, which is in fact a statement of the Erebor theme.Other sound effects used in Mirkwood and the Treasure Hoard scene, while non-diegetic, were performed by the orchestra and feature on the album.
