Epona's Song

Epona's Song is a reappearing song in the Legend of Zelda series. This pastoral melody summons Link's horse Epona when played in outdoor areas she can feasibly reach. When played to the cows found about Hyrule, they are reminded of "the pasture", and produce milk if Link has an empty bottle to store it in.

The Legend of Zelda: Ocarina of Time
Epona's Song first appears in Ocarina of Time. Link learns the song from Malon as a child, and can later use the song to tame the seemingly wild Epona in the future. Malon learned the song from her mother a long time before the story in the game takes place.

The Legend of Zelda: Majora's Mask
Epona's Song appears again in Majora's Mask, this time learned from Romani.

The Legend of Zelda: The Minish Cap
In The Minish Cap, Malon can be found in Hyrule Town. When Link approaches her, she sings Epona's Song.

The Legend of Zelda: Twilight Princess
In Twilight Princess, Link can play the song on a strange plant shaped like a horseshoe to summon Epona. However, this plant grows only in select areas. Later in the game, Link obtains Ilia's Charm, with which he can summon Epona from any place she can reach.
