Melody is the realm of music, for which many of the inhabitants are naturally inclined toward more than other people in the entire Magic Dimension.
Melody is full of mountains that are surrounded by forests with reddish leaf trees. There is an ocean near Musa's home, in which there exists the Ocean Gate linking Melody to Andros that is guarded by a Selkie named Sonna, as well as the Ruby Reef, which is filled with beautiful corals and a giant enchanted harp created from those corals that allow it to make beautiful music upon being played.
The King of Melody appears to be an obese man and his clothing is similar to Chinese clothes. He is the father of Princess Galatea. He and his daughter are present the Sovereign's Council in the Domino Royal Palace during the events of Season 5.

After she, Stella and Aisha used their Harmonix, Tritannus - who had forced his face through the Ocean Gate of Melody by absorbing the powers of Sonna, appeared and tried to turn Aisha into an monster, but Musa jumped in front of the ray and got turned into a monster instead.
Being chased by Musa through the ocean, Stella and Aisha hid in an cave and Lemmy got an idea of making Musa bond with Sonna to restore her to her original form. While Stella distracted Musa, Aisha got Sonna along with Lemmy.

Feeling abandoned from Icy and Tritannus, Darcy and Stormy stage their own evil deed - kidnapping the singing whales of Melody.
When the Winx enter the infinite ocean, the singing whales appear, bewitched by Darcy and Stormy and are ordered to finish them off. As the Winx get ready to defend themselves against them, Musa reveals that the whales are vital to Melody's survival. Musa then sings her mother's song and relinquishes them from the Trix's spell and the whales return to Melody.
The Winx return later to Melody and Musa joins her father and pines for her mother, thinking of using her Sirenix wish to bring her back but decides not to. Musa and her friends then return home and the whales wave goodbye to her.
