In the final lesson of the course, Simon explains how to identify, read and count the most popular 16th note triplet groupings. This is a new study area. While these fills may not be as prominent as regular 8th and 16th note options, they are essential to know, a lot of fun to play, and even more fun to orchestrate. While the video breaks down the three most popular groupings, the secret sauce here is in the audio file examples that round off the course, so whatever you do, don't miss them. Another course down, and more beats and fills in your repertoire. Great job!
