Sun's Song

The "Sun's Song" is a melody played in Ocarina of Time.

Learning Location
The song is composed by the Composer Brothers, Flat and Sharp. Assigned by the Royal Family of Hyrule to study the mystic powers of the family, this melody is the result of Flat and Sharp each studying a different song: one to summon the sun, and another to summon the moon.

The "Sun's Song" can be learned from entering the Royal Family's Tomb in the Graveyard of Kakariko Village; however, the inside of the tomb can only be accessed after playing Zelda's Lullaby on top of the Triforce mark. The notes for this tune are scratched on a wall at the end of the crypt along with a poem. The "Sun's Song," when played on either of the ocarinas, will allow Link to change night to day, or day to night. It can also freeze ReDeads and Gibdos inside the room within which the melody is played.

Uses
When this melody is played, one of two things can happen to the surrounding area and Link's location. In areas where time flows normally, Link will remain in his current location, whereas in locations where time normally stands still, Link is returned to the entrance to that area. Examples of these effects are Hyrule Field and Kakariko Village, respectively. When the "Sun's Song" is played in Hyrule Field, Link stays where he is, and the sun quickly sets before the moon is summoned. When this melody is played in Kakariko Village, however, the screen goes black, and when Link is visible again he is at the entrance of Kakariko Village. This song is especially useful for completing the Gold Skulltula token side quest, as they are only found on the overworld during night.

Since its introduction in Ocarina of Time, the Sun's Song has become the song to signify morning in almost every The Legend of Zelda game.

A more basic version of the "Sun's Song" appears in The Wind Waker, known as the "Song of Passing," which serves the same function as the Sun's Song.
