It would be a lot more interesting as a HoloLens or Google Glass app. Instead of being put into a game world, and attempting to play guitar, it would be better to keep the user in the real world and add a non-intrusive note track to the real world. Maybe instead of having an encompassing note track and fake room, just offer a view of the tabs that could be glanced at if you got stuck. Either that, or have the ability to stand up playing guitar, and have the note track move on the floor, so, in theory, you could just play normally and have the ability to look down for a quick reference. It would be a very niche thing, and expensive and time consuming to make, but it'd be interesting.
