I recently started to notice that a lot of the time Yngwie looks like he has his right shoulder raised when playing the guitar:
Maybe it’s just the way he is posed but nevertheless I thought I’d give it a go. To do this, I raised my arm placement slightly on the guitar which raised my shoulder.
First thing I noticed was that I could supinate my picking arm a little more and I had to raise my middle, ring and pinky to accommodate this so that they weren’t grazing the strings when I played. I found that compared to my original technique which looked like wrist and a tiny bit of forearm, I was getting a lot more forearm wiggle and playing faster was easier 
(Is the forearm mechanic considered to be faster than wrist?)
I thought I’d share this in the hopes that other people could experiment with it and see if they have similar results!



I know I’ve heard Troy and others mention that the elbow, for a lot of players, is the fastest mechanic. And indeed some of the fastest players (Batio, Cooley) use an elbow mechanic. But that could just be that since it only goes back and forth in one plane that it’s easier for most people to floor it. They may be capable of getting their wrist to deviate that fast, or their forearm to rotate that quickly, but lack the coordination to make that happen, without putting in enough work. These are fun questions!
