Epona's Song

Epona's Song is a song appearing in Ocarina of Time, as well as a few other Zelda games. Malon teaches it to Link at Lon Lon Ranch as a child.

In-game
During the day, Malon can be found singing the song at Lon Lon Ranch. She teaches it to Link, and the two discover that the song has a calming effect on the young horse Epona. As an adult, the ranch has been taken over by Ingo, who in turn has been overtaken with evil. Ingo lets Link ride horses inside the pen for 10 Rupees, and eventually challenges him to a race. Link can use this song to summon Epona. When Link wins, Ingo is furious. He promises that if Link beats him in a race again, he will give him Epona, and when Link does so, Ingo does give him the horse-- but also traps the two in the ranch. Link can escape by jumping over the fence on Epona. After this, playing the song calls Epona to him whenever she can reach.
