Watch the Natural Harmonics Groove online guitar lesson by Jennifer Batten from Rock Sauce for Rhythm Guitar
The thing to get into your head first is the rhythm of this groove. Take a small chunk at a time and play it slowly to get it under your fingers before adding speed. Notice in the second and fourth strikes that the notes are immediately muted. When you're playing the single note harmonics, you want them to all ring out together. When you hear the harmonics bent, it's coming from the whammy pedal pressed by my foot.
