These 8 drum beats will test your ability to add accented notes to the two handed hi hat pattern, whilst also negotiating tricky bass drum rhythms and open hi hat combinations.
Start off slowly and build it up when you are comfortable with the grooves at low speed. Improve your timing and measure your progress with a metronome. You should start as low as 40 or 50 bpm, but probably easier without a click, or double it up to an 8th note click, because the slow click will be tricky to play to.
