Anyone who works with firearms knows the problem if sympathetic grip - the right hand wants to do what the left hand is doing, which with guns is bad if your right hand finger is on the trigger and you attempt to grab something(or someone) with your left hand (obviously don’t do this).
With fingerpicking the bass I find that when I am alternate plucking, if there is a faster section that is rising in pitch on the fretting hand then I may skip an alternate pluck - like if I am going 1st to third fret (left index to pinky) then even if I’m supposed to pluck right hand middle then index, I switch and double pluck with my index on the note leading up and then pluck index middle.
I do the opposite if fretting is going down in pitch
So my right and left fingers are “moving in the same direction.” Does that make sense?
It is totally unconscious. I can stop it by concentrating and going really really slow and practicing the riff over and over, but if I come back to it after a few days and go righ to full speed I do it again.
