A popular effect to use with the shuffle rhythm is right hand damping (indicated by the symbol D). This is achieved by lightly resting the butt of the right hand on the strings near the bridge of the guitar while strumming, producing a slightly muted sound to the chord. Do not press too heavily on the strings as the chord will be completely muted creating a "dead" sound instead. This technique is applied to the following example.
The next example features the previous chords over an 8 bar Blues progression.
