The guitar is an extraordinary instrument in the hands of a master, But even for us good players, it gives a great deal of pleasure to us and our audiences.  I have reached the point where I would like to be a better player than I am now.  I may not become a “master”, but I do know that I could get a lot more enjoyment if I played at the next level.  It’s clear to me that I need to master the guitar scales if I am to really improve.  I have found an on-line guitar scales course that is making it easier than I thought it would be.
