Watch the Punk Pop Chords online guitar lesson by Angus Clark from Hard Rock Survival Guide: Rhythm
I'm not gonna lie, this is just a G chord, a D chord, and an A chord. And that's okay, because all you need to write a hit song is three chords and the truth. It's simple stuff but you have to play it right. If you had to track this guitar part in the studio, one of the biggest concerns would be getting the guitar tuned up right so that all three chords really sound in tune. Then you'd have to take a test run on it to make sure the manner in which you are choking the chords isn't causing a woof or any other noise that will interfere with your millions of fans' enjoyment of the track. Then, you're going to want to listen to the feel on the drums and make sure your eighth note is in the pocket. There's a quick sixteenth note figure using a move from an A chord to a D triad over the A bass note that is a test of your sixteenth note. Make sure to engage your right wrist in playing this exercise throughout. Where do you hear this kind of chording? Everywhere, from The Who to Green Day, Blink 182, Alice In Chains, Black Veil Brides, Motley Crue, you name it. This is straight up rhythm guitar with gain and volume, and you have to be able to nail it in order to survive.
