Watch the G Vamp Breakdown online guitar lesson by Robben Ford from Blues Revolution

Robben breaks down the previous one-chord vamp explaining that even though the chord is a G7, he is thinking and playing in the key of C. The notes G to G in the key of C, is the mixolydian mode.

Robben expands on several concepts ranging from slash chords to sus chords to voicing chords in 4ths across the pentatonic scale. There’s enough insight packed into this one lesson to ensure that your own one-chord jams will never sound the same again.
