Wondering how universal this is - but this is something I’ve done for a long time and picked up from a Vai interview. I forgot about it for a long time as well, but it kind of triggered some memories from being a teenager and working on cleaning things up.
To start out here this is not contradicting the start with speed idea - originally as a teenager, I just straight up tried to tremolo pick as fast as possible off the bat - which I did not try to build up at all, I followed the start fast approach naturally and drilled the hell out of it trying to get the physical limit even faster by doing chromatic patterns with a metronome.
When I think of starting slow and “gaining speed”, though, it means something a bit different.
This came a little later in terms of cleaning up technique and “working up” to speed on more complex picking patterns.
Basically - I’ll start a picking pattern slow, too slow to have the form right and there’s clear tension. I’ll repeat it, but when I do this I close my eyes and focus explicitly on relaxing my picking hand/arm as I repeat it and do some meditative breathing to help with the relaxation.
When I do this, typically my picking form will fall into a more “correct” and I’ll start speeding up as a function of relaxing.
I’ve been finding that even more effective now that I’ve drilled in different escape mechanics to try for different runs. I’ll start stiffly applying rotation or some escape and work on relaxing into a less tense form or motion, and typically get good results where the speed at which I can play cleanly is increasing towards my faster picking motion.
Curious if anyone else uses this to internalize clean picking patterns?
