Watch the Rhythm Mojo Groove 4 online guitar lesson by Shane Theriot from Rhythm Mojo
Often in a real playing situation, or when writing/playing a song, you don't need a lot of fancy chords or funky moves. This is an example of a simple two chord vamp - G major to D or D7. I'm only using a basic G major chord in the 7th position and moving around for the D shape. You can hear the way I imply the D dominant 7 sound every once in a while. (you may see me fumble for a chord, sometimes when I hear parts in my head my brain moves quicker than my fingers!) I then move on to an arpeggiated part using the same shapes - (Breaking up the Chord). For an extreme example of this technique, (sometimes using a capo, or open tuning, but often over this same progression) check out some of the great African guitar players like Ali Farka Toure' or others.
