Song of Healing

The "Song of Healing" is a recurring song in the Zelda series, first appearing in Majora's Mask.

Majora's Mask
In Majora's Mask, the "Song of Healing" is taught to Link by the Happy Mask Salesman after Link, cursed into the form of a Deku Scrub, retrieves the stolen Ocarina of Time from Skull Kid. The powerful notes of the song heal Link's soul, and the young hero returns to his Hylian form. A mask materializes and is kept as a memento of his time as a Deku. Link utilizes the song many times thereafter, as it has the mystical capability of healing a broken soul and giving peace to those who cannot forget.

Frequently, using the "Song of Healing" on tormented individuals yields a mask. The proud Goron warrior Darmani and the brave Zora guitarist Mikau each grant Link the use of their mortal bodies through transformation masks in return for his promise to aid their people. The spirits, finally at ease, depart to the afterlife as Link watches over their graves. The "Song of Healing" is also used to heal Kamaro, a dancer's ghost outside of Clock Town, and the researcher in Ikana Valley.

Twilight Princess
In Twilight Princess, the Golden Wolf that teaches Link the Shield Attack is summoned when Wolf Link howls the Majora's Mask version of this melody at Death Mountain.

Spirit Tracks
A song under the same name makes an appearance in Spirit Tracks, learned at the entrance to the Forest Temple. If it is not learnt there, there are other opportunities at the entrances to some, but not all of the other temples. However, the song itself sounds and functions entirely different. Playing it with the Spirit Flute while in a dungeon causes the Spirit of Healing to come and heal Link completely, but it can only be used once per dungeon.

Trivia

 * In Majora's Mask, playing the "Song of Healing" for Sharp will have him remark that, while the song has sounds somewhat soothing, a song like that has no longer effect on someone like him.
 * Also in Majora's Mask, if the Song of Healing is played before speaking to the Poe Collector in the Spirit House, he will lower the price from 30 to 10 Rupees, while commenting that not all spirits can be healed by that song.
 * If Link cuts up a wooden sign in Majora's Mask, the "Song of Healing" can be played to repair it.
 * The notes in the "Song of Healing" of Majora's Mask are the same as Saria's Song, except they are reversed.
 * Oddly, when Link plays the song in the European version of Spirit Tracks, it says that he played the Song of Recovery.
