Zelda's Lullaby

"Zelda's Lullaby" is a recurring song in the  series. Since its debut in A Link to the Past, it usually serves as background music whenever Princess Zelda appears and is thus considered to be her theme song. It appears as a playable melody in Ocarina of Time and Twilight Princess.

A Link to the Past
"Zelda's Lullaby" plays in the background when Link meets Princess Zelda for the first time and whenever Link rescues one of the Seven Maidens.

Ocarina of Time
"Zelda's Lullaby" is taught by Impa after initially meeting Princess Zelda at her courtyard in Ocarina of Time. It is a sacred song with mysterious powers passed down by the Royal Family for generations, and it also served as a lullaby for the young Princess Zelda. "Zelda's Lullaby" plays a major role in solving numerous puzzles in the game, such as raising water levels in the Water Temple, to entering Zora's Domain as young Link, and opening other hidden passages. The mark that usually signals the need to play "Zelda's Lullaby" is a Triforce symbol, as seen when opening the Royal Family's Tomb and changing the water levels in the Water Temple.

According to Impa, only members of the Royal Family are allowed to learn "Zelda's Lullaby"; as such, playing this tune helps prove Link's connection to the Royal Family. After Ganon has been defeated and Link and Princess Zelda are talking in the sky, the princess sends the young hero back to his original time by playing "Zelda's Lullaby" on the, further demonstrating the melody's mysterious powers.

Majora's Mask
In Majora's Mask, "Zelda's Lullaby" can be heard as background music during the flashback scene where Princess Zelda gives Link the Ocarina of Time.

The Wind Waker
"Zelda's Lullaby" is played in The Wind Waker when Tetra is revealed to be Princess Zelda. Furthermore, it is heard during the staff credits as part of the ending theme.

Four Swords Adventures
Similar to A Link to the Past, "Zelda's Lullaby" plays after Link rescues one of the Seven Maidens.

The Minish Cap
"Zelda's Lullaby" occassionally plays when Princess Zelda and Link go to the Picori Festival in The Minish Cap. It also appears when Zelda first visits Link's house and during the ending credits.

Twilight Princess
"Zelda's Lullaby" appears as a playable melody again in Twilight Princess. Upon first entering the Sacred Grove, Wolf Link must howl the lullaby in order to make the Skull Kid appear. Once Link defeats him, the Skull Kid will open the way to the inside of the grove. He must howl it again after he reaches the inner part of the forest to activate the guardian statues and solve their puzzle to access the path to the Master Sword.

Zelda's theme is also heard on both occassions that Wolf Link meets Zelda inside her chamber in Hyrule Castle, and it's played once again when Princess Zelda receives the Light Arrows from the Light Spirits and asks Link for his help. A distorted version of "Zelda's Lullaby" can be heard when battling against Puppet Zelda.

Phantom Hourglass
A darker version of "Zelda's Lullaby" is played in Phantom Hourglass when Tetra pleads for Link's help as she gets swallowed by the Ghost Ship. The normal tune is later heard after Tetra returns to normal inside Linebeck's ship.
