Triplets are used in many styles of music including blues, rock and country. The basic shuffle rhythm is created by leaving out (resting) the middle note of each three-note triplet group. This “triplet” idea allows performers to include triplets in the melody without clashing with any rhythm patterns.
Many shuffle rhythm songs are in 12/8 time (sometimes called “swing time”) which is just like 4/4 time except with a “swing”. Here we’ll take a look at a common blues shuffle rhythm in the key of A using power chord shapes.
