Song of Healing
From Zelda Wiki.org
The Happy Mask Salesman will teach you the Song of Healing after you get your ocarina back from Skull Kid. With this song you can heal a broken soul and give peace to those who cannot forget. It is used to get the Goron Mask, Zora Mask, and remove the Deku Mask at the beginning of Majora's Mask. It can also heal Kamaro, a dancer's ghost outside of Clock Town and the researcher in Ikana Valley. Playing it for Sharp will have him remark that, while the song has something soothing, a song like that has no longer effect on someone like him.
In Twilight Princess, the Golden Wolf that teaches you the Shield Attack is summoned when Wolf Link howls this tune at Death Mountain.
The song's notes are: B A F B A F B A E D E
