I have completed the Core Fundamentals 2 course. I had a basic knowledge of the major scale, minor and pentatonic going into the the course but I picked up a lot along the way that filled in the gaps.

I'm now working through the Rock I course which is also outstanding. But, I want to gain more skill and knowledge in theory, scales, etc.

What would a good Scale lesson to tackle next after the Core lessons? I'm leaning towards Major Scale Patterns and Positions by Schlegel. Would that be a good next lesson?

Thanks!
