Yngwie definitely does some things with arpeggios we would consider inefficient. Look at how he plays that minor 5-string shape:
You can see that reasonably clearly in “Play Loud”. Those two downstrokes in the descent kinda don’t make sense, but they happen. It’s hard to tell even in the slow-mo but they look like hops or escapes rather than swipes, but there’s no way to be sure of course.
The way it makes sense is: the descending up-up-down pattern from his 3 string arps always applies, and he glues the rest of the pattern on the lower strings to it, regardless of what most efficient picking pattern would be. He probably has a couple of other combinations down there a bit like the famous “volcano” lick, we just don’t know what they are yet.
I was applying that approach to the shape we are talking in Icarus Dream:
It feels funky at first but if you’ve got the 3 string arp patten down, it starts to feel pretty natural. So I agree with @joebegly, but I’d start on an upstroke (personal prefs as he says).
And yeah, @ASharpMajor, all the tab is wrong in some way, even the better ones. I have all the early Hal Leonard ones Wolf Marshall did, and while the notes are mostly right, it’s clear Wolf had never seen Yngwie play. Things that are obvious when you know YJMs idiosyncrasies are missing. Even LuckyMojo’s brilliant Far Beyond The Sun tab (there’s a thread on here if you haven’t seen it) turns some of the Fm arps into mad stretchy EVH licks!
