If there’s any advice I could give there it’s to maybe not spend quite as much time doing all that at a slow speed. I used to spend so much time with a metronome going slow, but I think at this point that’s only really effective at getting the notes memorized, because there’s a lot that changes when you start getting up to tempo. The timing of things and which direction your pick is moving, namely. When you have all the time in the world you’re not even thinking about that pick traveling from one note to the next, and you get an odd sense of the timing because it’s not being played at tempo over the beat. Then you try to play them up to speed and none of it makes sense, you feel like you spent hours learning nothing.
Hahahah that whole intro to Cliffs Of Dover is a crash course in that. Those descending cascades sound nothing at all like that played at slow tempos and I was alternate picking the entire thing before I attempted it at tempo.
So even if you bomb the shit out of it and only get a few notes right each time, don’t be afraid to play around at tempo or 3/4, because you’ll start getting little glimpses of how it’s supposed to sound/work. That’s really all I’m doing in that vid, I already learned what notes to play, I’m just bashing it in my head until I get to them all cleanly and smoothly, it’s often easier to let my fingers figure that out on their own rather than me sitting there trying to analyze it.
