Sonata Dusk, an air-headed and quirky backup singer of The Dazzlings and a siren in disguise, was at the Starswirled Music Festival, eating with her fellow Dazzlings, Adagio Dazzle and Aria Blaze.

She is a siren, but in human form, she has purple and sky blue hair pulled in a ponytail, burgundy eyes, and pale blue skin. Her attire includes a magenta vest, matching wristbands, a pink skirt, and pink high-tops worn over matching socks. She loves tacos. She is a member of the Dazzlings, who was led by Adagio Dazzle and Aria Blaze. She and her fellow Dazzlings wore red pendant necklaces that provided them with the ability to sing and enchant humans into fighting and following their bidding. Unfortunately, they no longer have them because they were fractured and destroyed during the Battle of the Bands.

Hehehe... for realsies... I'm sooo bored! I want tacoes! Hehehehe! Sonata said and giggled.
