This is kind of a general question, but I’ll try and relate it to my personal experience. I’ve been playing for 20 years, so I have a pretty well formed picking technique. I’ve spent a lot of time trying different pick grips and wrist motions, mostly from the perspective of timbre over speed, which is a big reason I pulled the trigger on this site.
I can play from the elbow in a trem as fast as I think I’d ever need to, trapping the pick on both down and up strokes (figured that one out when covering Miserlou). Every other motion I’ve tried with guitar is topping out about 130bpm 16ths or slower. I suppose I could go all in elbow, but it’s always a bit sloppy, and hand synchronization and string changing are a bear.
The other motions I typically use I’m pretty sure would fall in to the categories of ‘plausible’ picking techniques, and I feel like my hand is capable of more, but it’s almost like the resistance of the pick on the string is catching up the whole thing.
Instead of looking for a critique, I’m wondering how students should proceed from that point if they feel like they aren’t up to par on the tremolo test? How fast would you want to be to proceed?
OT, but I’m also about ready to give up playing after watching the first timer hitting 180 on day one. I’m not sure my ego can recover from that one!
