Watch the My Turn online guitar lesson by Brad Carlton from Groove Builder
This track is simply a straight sixteenth note funk groove with C7 and G7 being the chords. Notice how the bass line is played with variations throughout. This prevents boredom and allows for creativity between the drums and bass. Sometimes the most important thing is what you don't play, meaning you don't have to "throw in the kitchen sink" at the end of each four bar phrase. Restraint is the operative word here. Many times when you're tempted to play a fill - don't! You'll be amazed at how much this mature musical concept will improve you artistry.
