Watch the Swing Pop online guitar lesson by Vicki Genfan from 30 Strumming Patterns You MUST Know
I'm playing Am-C-G-D. This pattern's got a tight, pop feel. It requires both left hand and right hand muting to really give it the punch. The right hand mute uses the palm. You may already be familiar with it, but if not - spend the time to get it right. This is a technique you'll be using over and over as a rhythm guitarist.
