i am trying to learn the solo from dying in your arms by trivium and i have no idea how to play the fast bits. i have a movie of corey playing it and he just looks like he is strumming the guitar and moving his fingers around.

is this a technique or a type of picking or something?
i have no idea so any help would be good.

heres the tab-

E|--------------------------------------------------------------------------------------------------------|
