From Zelda Wiki, the Zelda encyclopedia
Songs have been a recurring element in The Legend of Zelda series.
Types of Songs
Most of the console songs that assist in moving around the overworld, besides warping songs. The most notable songs here are Epona's Song, which calls Epona to Link, and the Wind's Requiem, which allows for easier sailing around the Great Sea.
Time Altering Songs
There are many songs that can alter the flow of time or even allow moving forward or backward in time.
There are several songs that usually have one specific purpose that are used in a small number of special circumstances and then rarely, if ever, used again after that.
