As the name suggests, this is Edward's theme. The song is also called "Melody of Lute" or "Edward's Lute", despite the instrument being a harp. Hm, odd. But I'm not complaning, I absolutely ADORE FF4's harp sound!! It sounds gorgeous and is used in a multitude of songs other than this one, such as Trojan Beauty, Theme of Love, Land of Summons, etc.
