Here's a set of basic patterns for making a 70s-style triplet groove, or a moderate, triplety, shuffle,, as you hear on songs like Isn't She Lovely, How Sweet It Is To Be Loved By You, Higher Ground, or Lopsy Lu. Nobody likes working on this style— as I noted before, a combination of factors make it a more challenging style than it appears— but it does come up if you're working commercial jobs, and it's a drag to get caught unprepared. Work on it a bit, and you'll kill it.
Play each of the patterns as written, then combine parts. Start by learning each of the cymbal variations along with each of the bass drum variations, then play each of those patterns with all of the snare drum variations.
