The game starts like a cartoon of sorts and throws you into a musical interlude where you battle other musicians. If you take Street Fighter and Guitar Hero (only with piano) and mash them together.. This is what you get.
There is humour and although I'm currently playing through it on easy, I am missing a few notes. It takes some practice so stick with it. The music is catchy, and is re-interpretations of classical music.
Interesting story between "matches?" with humour and some versions of some popular musicians that you will recognise almost instantly.
The Multiplayer mode is lacking friends to play with, but I'm sure if you have friends with it you can battle each other. I was unable to find anyone when searching in the lobby.
