The role of these pieces within the structure of the music of the Lord of the Rings is arguable. While they weren't composed by Howard Shore, they often were accompanied by the score: The second verse of "Edge of Night" was accompanied by the string section and picked up by the clarinet, Gandalf's performance of the Old Walking song was harmonized by the orchestra, the underscore to both of Enya's compositions was orchestrated and conducted by Howard Shore. The fiddle accompaniment of the Drinking Score is even featured in the live performances. All of those pieces (excluding "rock and pool" as well as what are outright effects like horn calls) are even featured on the album. Some of it, like Aragorn's coronation chant, even appears in the Lord of the Rings Symphony.
