Watch the Comping the Shuffle online guitar lesson by Robben Ford from Blues Revolution
While playing the same chord and rhythm pattern is a recipe for boredom, playing too much is just as bad. In this playing example, Robben demonstrates how to balance variation with consistency by varying the rhythm guitar figure for each 12-bar section. Once the new figure is established he stays consistent within the section.
Make the soloist sound good and you can bet on keeping the gig.
