When working on these loops, try to get references from records in this style: listen to the drummer but also to the entire group. Do not reduce your vision, music is a whole, and the only way to understand any style is with thorough analysis. Here we are working on a kind of ternary pattern, that is, based on triplets, in this case a Shuffle. Just observe how I develop different breaks or accents, but always looking for the groove. Listen to Jeff Porcard or Steve Gaad, who are masters of this style.
