I’m not super familiar with the phrase or Govan’s technique… but simply looking at hte notes, a few things jump out:
*The opening notes, pretty munch to where you notate in red, lend themselves to a single escape picking movement, specifically escaped upstrokes.
*the four notes in red do NOT. Nor do they lend themselves to switching from escaped upstrokes to escaped downstrokes, since the first note would be a downstroke (which would be buried) you’d need to change strings after, and then for a couple notes it’s one note per string. You can’t really switch from escaped upstrokes to escaped downstrokes for a bit here since you’d need to switch pretty much every note. A “escape hatch” pulloff to the 15th doesn’t really work here, you could sweep the next two notes, but not the final 16th.
*This suggests two possibilities - the tab could be wrong (and again, I don’t know the original) and this could be different from the way Govan plays it… or he’s doing some sort of crosspicking/double escaped motion here.
I have no idea what his actual motion looks like and how exactly he’s doing that… but if you want repeated one note per string playing, it’s either slow enough that you can fudge it, or he’s using a double-escaped motion.
