This is really a questions, so much as I found a resource on pentatonic scales that I thought I would pass on.
I was working on Man of Sorrows last night. I was working on the transposition of the piece and was confused by part of the explanation. However after listening to that part of your explanation, I heard the “practice the f pentatonic scale. So I did that and was able to easily transpose the piece.
Because I’m a theory junkie, I got to think about the structure of pentatonic scales. Well as usual the internet reveals all. I found this website on pentatonic scales, that others might find interesting.
