The majority of the characters and places in this game are named after various musical references.

The PlayStation 3 version of this game features many additional contents not found in the Xbox 360 version. One of the key features are Prince Crescendo and Princess Serenade as playable characters in battle for the first time. Both of them were just event characters in the Xbox 360 version.

If you look closely at Prince Crescendo's back where his cape is, you'll see the tri-Crescendo emblem. The developers created this character in reference with the game's story and the companies' name themselves.

The story is divided into eight chapters, with each chapter being represented by one of Chopin's compositions, and being related to events within his historical life.
