Ballad of the Goddess

The Ballad of the Goddess is a song featured in Skyward Sword. The melody and lyrics of this song have been passed down for generations in Skyloft. The ballad is heard many times throughout the game, but is notably sung by Zelda on the day of the Wing Ceremony.

Link learns the song from the old woman in the Sealed Temple after obtaining the Goddess's Harp. The woman tells him that the lyrics of the song can be used to locate the Sacred Flames, which Link must find to strengthen his blade. Link can learn the lyrics from Gaepora, which reveal that the two large windmills in Skyloft must face the Light Tower. Once that is done, Link must play the Ballad on top of the tower to reveal a path into Thunderhead.

Lyrics
Oh youth, guided by the servant of the goddess, unite earth and sky, and bring light to the land.

Oh youth, show the two whirling sails the way to the Light Tower...and before you a path shall open, and a heavenly song you shall hear.
