The discussion is a little tossed off–as if we’d already been looking at that aspect of his technique, but I can’t find that antecedent discussion. I get the the sweeping and cross-neck stuff, but the thing about moving up or down the neck to get the off-kilter effect of three-note patterns without breaking the UPS 4 note-per string rule is really fascinating and there’s just barely a taste of it. There’s some in the Yngwie stuff, but I’d love to see more on how Eric uses it. Is there a real breakdown of it somewhere?
Apologies if I’ve missed something obvious–I’m new to the site and still finding how to navigate around in it.
