Harmonix is officially working on Dance Central 2 and new weekly downloadable content for its Rock Band universe, but it appears the Boston-area music game developer may also be rocking out to another tune. Is Vidrhythm the name of a new Harmonix music game?

　　Harmonix has filed a trademark (via Siliconera) with the United States Patent and Trademark Office for something called Vidrhythm. The title is listed under the goods and services description of "video game software; downloadable video game software; video game discs; video game cartridges; protective carrying cases for mp3 players and cell phones."

　　As of press time, Harmonix had not responded to GameSpot's request for comment on the matter. However, the title Vidrhythm certainly sounds as if it will remain in the music genre for which the developer has become known.

　　Harmonix--located in Cambridge, Mass.--has created a range of music games since its inception. The studio developed the first Guitar Hero title, Amplitude, and Frequency, as well as the critically acclaimed Rock Band and Dance Central franchises.
