A demo version of the Microsoft Xbox 360's Eternal Sonata has been released on Xbox Live Marketplace. The bite-sized sample of the RPG from Tri-Crescendo, the developers behind Baten Kaitos and Baten Kaitos Origins, has been slung online in the run-up to the game's September 17 release in North America.

The story centres on the death of legendary pianist, Frederic Chopin. Prior to popping his clogs, the great musician envisages a fairytale land in which individuals suffering from incurable diseases are bestowed with magical powers. He meets a young girl Polka after travelling to said fairytale world and, as is the norm for RPGs, much adventuring, battling and levelling up ensues.
