E1: |-5-6-7-8-|
Play that with the four fingers I assume we all use. But as you hit the notes you don't remove them from the fret. None of the fingers. So when you've played all four notes all four fingers should be pressing down the 5,6,7 and 8th fret.
You continue by playing the same run on the B-string. So when you play the first note (fret 5) on the B-string the remaining three fingers should still be on the E-string. And when you play the second note (6th fret) the remaining two fingers from the first run should still be on the E-string and so on. Dunno if this is helpful at all since I haven't played this one frequently.
Don't look at me, swan!
