Ryan Adams - Answering Bell intro

Hi all,

I am very much a beginner and so I need a little help. I'm trying to figure out the tab to the into to this song. I don't need the whole song but would love to figure out those first couple measures before the lyrics start. I think it's very simple but maybe someone can help speed up this process for me? :)
