Watch the What You Don't Play online guitar lesson by Corey Congilio from Rhythm Factory: Texas Blues
Most people probably know some type of rhythm like this. In this example I wanted to show you that you don't always need to keep the root note droning to pull off an effective rhythm like this. We're in the key of A here but, this idea is easily moved to any key. Also, less is really more in most cases so, let the bass player handle the root note. Also, notice how I play the riff in a very staccato fashion. This keeps it funky!
