This has been the best run-down of the theory behind this track I have seen and I found it fascinating. My favourite bit is when Rick plays along some jazz chords on a six-string. I felt he took something extraordinary and explained the ordinary behind the scenes element very well. In the end it is music and it abides by certain rules no matter how clever. I still don’t grasp theory or dots on a stave but my ears are good and presentations like this make me feel a little bit closer to the musicians I love to listen to.
