Essential Rudiments - If you’re new to rudimental drumming, we’d recommend that you take a few minutes and watch John’s video lessons on “How to Learn and Practice the Rudiments” and “The Real Rudiments”. Instead of working your way through the rudiments in order that they appear on the list, consider John’s “4 Tier” Rudiment Learning Sequence which will help guide you as you progress from one to the next.
