Nintendo needed to be choosy about what went in the game and subsequently chose only music that would advance the story or mood. From the tranquil opening theme that accentuates the lonely figure of Link on his horse to the heart-tugging background melody when Link first leaves the Kahri Village. They are all perfect examples of using music to draw the player into the game. But it gets better. Hyrule is filled with all the ambient sounds you'll find in the real world.
Birds sing in the background, crickets chirp, there is always the faint sound of flowing water.
Anything that would provide mood was tossed in and used perfectly. This is all possible because Zelda was provided in surround sound. Zelda tops all comers in its emphasis on exploration and discovery. Traveling through the Land of Hyrule, I was blown away by the depth of the land. Far away building looked distant and it could take several real-time minutes to walk from one end of the land to the other.
