Hmmm. Any that I can play on my ocarina.
Gerudo Valley, Ballad of the Windfish, Ballad of the Goddess, Grandma (from WW), and Sheik's theme.
And Tapion's Theme from the Dragon Ball Z movie Wrath of the Dragon.
hehe Tapion and Link. What a pair. Simply put, both are heroes, both have magic ocarinas and swords and both have travelled through time. Ironically, Wrath of the Dragon was released 4 months before Ocarina of Time was.
