@tommo, I’ve been working a lot with your Yngwie 6s etude, as you know. (And don’t try to dissuade me! One issue I’ve run into is that, especially since each lick begins on the left hand with finger #1 (1-4-3-1-3-4 and 1-4-2-1-2-4), playing the lick in isolation can lead to clamping finger 1 down for the entirety of the lick. If you’re running it over and over, it starts to feel pretty tense - seems like a good way to injure yourself.
Interestingly, when I run the whole etude at once, I tend not to leave finger 1 down. Strictly speaking you could - and doing so might even make for better, ‘economic’ movement. But like I say, it doesn’t feel good. And what’s more, I’m anyway getting away from thinking that the left hand has to move with minimalist precision - seeing some vids here (Shawn Lane?) and elsewhere on YT, I see guys high-stepping their fretting fingers without ill effect. Two pretty good players I follow actually said explicitly, don’t worry about the economy thing; it’s basically a red herring.
So I’m thinking about practicing those 6s licks with lifting of finger 1, just like fingers 2,3 and 4. Anyone see an issue with that?
