the one way to do this to practive is createing nonsense arrpegios...just trying to make ur figners hit random notes..the goal is the get the notes to sound clean and in succesion(one by one)...if u have a fender oput ur pickup selctor onto the one nearest the neck cuz it removes any excess string stuff dum didiidildildidllid...what i do is to not look at ur fingers but ur picking hand and try syncing the random ntoes..slow down..or speed up cuz if ur too slow you will pick one string at a time...u dont want that
