Watch the Octave slip online guitar lesson by Jeff Scheetz from 50 Blues Rock Rhythms You MUST Know
Octave shapes are an important technique to master and this riff will help with that. Whether you are doing a Wes Montgomery style tune or more of an Indie rock thing, having the ability to slide around with your octave shapes is valuable. Remember to use your first finger to lay on the next string over and mute it - that way you can still strum through the three strings, while actually only sounding the two that are playing the octaves. Octaves make a great substitute for power chords when you don't want as much harmonic information to sound out in your riff.
