Watch the 16th Notes online guitar lesson by Brad Carlton from Groove Builder
This groove is based on the constant sixteenth note rhythm popularized by the great funk group "Tower of Power". Section A is simply an E7, section B is a C7. Later in the tune you'll hear us "open it up". This is where the rhythm section gets to solo.
Even if funk isn't your bag, there's no better learning ground for developing solid rhythm chops. You'll also find that the sixteenth note patterns so common to funk are also very evident in a wide variety of styles.
