Color Coded Music

Instead of the traditional black notes on white pages, some students are now being taught to recognize the color 'instead of' or 'along with' the location of the notes on the sheet. I think this is a bit strange overall since given some general information on reading music, after knowing the key and tempo - all that would be needed to play any set of music is the spacing and the color... not the 'notes' or the lines.

Ironically, while coloring general text is not patented - the coloring of musical notes is under a US Patent due to it's use as a teaching emplimentation.
