This is a basic flam pattern that more variations can be built from. Good for all drums and all people (snare, quads, bass, and people looking to play those things). It will require precision in your flam execution. You can do it! If you’re looking for a PDF of this exercise this is it! The second time through isn’t just a repeat, it’s off the left hand.
If this feels over your current ability — Break it down. Start slow and build it up. Start without the flams and without the accents. Play the sticking with plain 16th notes. Once that’s solid and even at a variety of tempos add the accents, and do the same. Once that’s great then add the flams.
