Sharp

Sharp the Elder is a recurring character in the Legend of Zelda series. One half of the Composer Brothers, Sharp is the elder brother of Flat. In life, Flat and Sharp were court composers to the Royal Family of Hyrule. After they died, they continued to linger on in the mortal plane as Poes.

Sharp's appearance, being slightly larger than his brother and wearing reddish robes, is an obvious reference to Mario, the brother of Luigi (whom Flat resembles) from the famous Super Mario series of games.

The Legend of Zelda: Ocarina of Time
When Link examines one of the gravestones in Kakariko Graveyard, Sharp appears and attacks him. Link defeats Flat's ghost, who surrenders and tells him about the history of himself and his brother, and how they came to write the "Sun's Song", a mysterious song that holds the power to control time. Link enters the Royal Family's Tomb and finds the notes to the song etched into the door leading to the Royal Family's crypt. If Link encounters Flat again, he further explains to Link the mechanics of the "Sun's Song".

The Legend of Zelda: Majora's Mask
Prior to the events of the game, Sharp and Flat were composers held in high regard in the kingdom of Ikana. However, Sharp succumbed to the wiles of evil and betrayed his brother. His brother, Flat, swore revenge against his brother's betrayal, and to this end, he composed a song known as the "Song of Storms", suffused with the sadness and anger he held against his brother. Both eventually died, but were revived as ghosts by the Skull Kid.

Link eventually comes to Termina and finds the grave of Flat, who teaches him the "Song of Storms" and asks him to cleanse his brother of evil. Link enters the Ikana Valley, where the water has dried up. He travels to the small cave that serves as the source of Ikana's water. Suddenly, the voice of Sharp is heard and the ghost of Sharp manifests himself. He tells Link to leave the cursed land of Ikana, and starts playing a song known as the "Melody of Darkness", slowly sapping Link's health. Link plays the "Song of Storms", dispelling the evil from Sharp's heart. Sharp realizes his terrible mistake and begs his brother for forgiveness. He thanks Link for breaking the curse placed on him and departs from the land of Termina.
