Epona's Song is a recurring song from The Legend of Zelda: Ocarina of Time and will become a frequent stapple of future Zelda games including Twilight Princess. The song is used to summon Link's horse, Epona in areas where Epona can reach (such as fields but not in cities). In some instances, you can play this song for Cows and they will give you milk if Link has an empty bottle.
In Majora's Mask, Link learns this song by visiting Romani Ranch. To get there, Link must either wait until the last day when the path has been cleared to the Ranch or he must return with a Powder Keg to destroy the rock early. Once the song has been learned, the path does not need to be cleared again to gain access to Epona.
