Wind's Requiem

The "" is a Song in.

Learning Location and Uses
The "Wind's Requiem" is learned upon reading Zephos's monument at the Wind Shrine behind Dragon Roost Island with the notes inscribed on it. This melody allows Link to control the direction of the wind, but it only works outside in the overworld.

The "Wind's Requiem" plays a major role in, for it is necessary to constantly change the direction of the Wind in order to navigate the many Islands of the Great Sea, as well as to favor flight with the Deku Leaf. In later parts of the game, playing this melody on NaN Wind Crests will make a Treasure Chest appear, usually containing a Triforce Chart in the Great Sea or a Treasure Chart in some dungeons, having a similar role to "Zelda's Lullaby" in.

In, the "Wind's Requiem" is no longer needed for sailing once the Swift Sail is obtained. The upgrade automatically changes the direction of the Wind to the King of Red Lions's heading.

Trivia

 * Interestingly enough, the "Wind's Requiem" can be used to change the direction of the Wind during the final boss battle against Ganondorf on top of TWWHD:, although doing so does not change anything with the outcome of the battle.
 * "Epona's Song" has the same directional notes as the "Wind's Requiem". Its tune is also similar to the first three notes of the "Song of Time".
 * Similarly to "Zelda's Lullaby", the "Wind's Requiem" is another alleged reference to the Triforce, with one directional note for each crest of the Triforce.
 * Contrary to popular belief, the "Wind's Requiem" can be obtained as soon as the Wind Waker is acquired. If the song is played at the start of Dragon Roost Cavern (the room Link obtains the first Empty Bottle in), the Wind will blow in one direction continuously until Link either leaves the room or falls in the lava.
