After 21 years of teaching private piano lessons, I found that for some students learning to read music became a roadblock. Many of them loved music and had talent, but reading traditional music notation was too frustrating, and their brains just didn't work that way! So I thought, maybe there's another way. I put all the method books away that I had taught out of for years, and placed a whiteboard between my piano and the wall. Instead of lines and dots, I drew letters and diagrams so the student could SEE what to play without any prior musical education. The results were phenomenal.
