OK, thanks to Mark and Howie I think I pretty much understand. It was just striking for me to see someone play that fast without using what I've always considered to be widely accepted as "proper" technique. I think Gary Moore is similar in that regard as well no?
For me, not using my pinky isn't so much a matter of not wanting to play properly as it is the fact that it's nearly impossible for me to do. After I shattered my hands when I was 13, the pinky on my left finger has a significant cant towards the ring finger and is in fact, bent. The tendons or ligaments or whatever is in there actually pull it more so, the farther I try to stretch it outwards/away from the rest of my fingers (Maybe tomorrow I'll take a picture and show you what I mean). The result, is that I go out of my way to NOT use it, as, unless it's a close ratio chord shape, it won't go where it needs to go.
Bottom line though, is that I was encouraged by this development. It made me realize that even without using it, it is physically possible to play like he does... which is something I find myself being more and more interested in the longer I hang around this place.
As I've mentioned before, this forum has really and truly benefited me as a player, it has challenged me to tread into territory that I never would have otherwise and I've been blown away to realize the things I wound up being capable of, that I assumed I never would be.
So, now, I'm going to watch that video about a million more times and start seeing how much of that stuff I can actually pull off on my own.
Thanks guys!
