In this pattern we'll be playing those octave chords we mentioned earlier. Keep in mind to mute them properly with your fret-hand index finger.
Use alternate strumming as you can see me doing in the video (down,up,down,up, etc). If you look at the tab you'll see that these octave chords are all sixteenth notes. However, watch out for the 2nd beat in the last measure, where you'll also play some quick thirty-second notes.
