Flat

Flat was one of the two Composer Brothers that haunted the Kakariko Graveyard in Ocarina of Time. They created the Sun's Song, which calls upon the Sun and Moon. When Link visits the Royal Tomb, the two Composer Brothers attack, but then realize Link is good after he defeats them.

Flat's Terminan counterpart in Majora's Mask is nearly identitical. Flat is the one of the two Composer Brothers that was locked up beneath Ikana Graveyard. He was locked up there by his own brother Sharp, and guarded by an Iron Knuckle. Link saved Flat, who taught him the Song of Storms, a song he had composed and that could cure Sharp of his curse.
