Saria's Song

Saria's Song is a recurring song in the Zelda series and in Ocarina of Time. As the name implies, Saria teaches the song to Link, and it can be used to talk to Saria throughout the game.

In-game
Link learns the song in the Sacred Forest Meadow, taught to him as a symbol of friendship by Saria. Playing it allows him to speak with her at any time. It also cheers up Darunia, convincing him to give Link the Goron's Bracelet. The song also helps him befriend Skull Kid and convince Mido that he's Saria's friend so he can get through.

Trivia

 * While Ocarina is the first game where this song appears, it appears in many subsequent Zelda games, played in the forest.
