Middle Root Note Method is designed for people to play keyboards with Simplified Notation or Digital Common Notation.
The main benefit is that you can play all keys with the same fingering as in C.
The core of the method is to move the root note of a key to that of Middle C.

I have consolidated my blogs on music notation into a wiki. It contains key mappings and analysis of the notation.

My intention is that if I am expanding the notation. I will update that wiki. Otherwise, I will post here.
PS. I tried to put it into Blogger.com. It is hard work. I wasted hours just to get the format right and it is really the wrong tool for this job as I need to include a lot of diagrams and to update the article as I go.
