So I brought up Van Halen in another thread, and I went and looked at some live video and found something I hadn’t previously realized.
Even though Eddie famously does a very unmistakable “forearm rotation” mechanic in certain tremolo picked parts, he does a bunch of other fast picking stuff that has a strong wrist flexion/extension component, and sometimes a clearly visible elbow component. I hadn’t thought about this much before, partly because A) I don’t associate Eddie strongly with alternate picking, and B) I watched so much Van Halen in my “pre-code” days that it never really occurred to me to go back and look at his technique through CTC eyes.
I think it also plays into the point that CTC isn’t so much a prescription per se, but a set of tools for explaining and understanding what elite performers do, even in the case of someone like Eddie, who fluidly jumps between different picking techniques, surely driven almost entirely based on intuition developed over thousands and thousands of hours of playing. Even if Eddie didn’t think analytically about the various techniques he so seemlessly integrated, the rest of us can gain insight from understanding the building blocks that he was playing with.
