So I'm a bit confused by the title. Is the game going to teach people how to play musical instruments or is it going to teach musical theory?

Or, more likely, is it just a game that uses music as the power aspect for the PCs? So in the end you are still just clicking mice and mashing keybindings.

From the description they provide, I think it's musical theory and composition... represented through keyboard and mouse mashing...

I didn't see any information related to unique controllers/interfaces, which would probably be pretty key to mention if that was the case.
