I've written out this groove in half time (quarter notes on the hi-hat, instead of 8th notes) to help you learn the co-ordination. Take your time with each bar on it's own and then try playing the first two bars joined together and your playing the finished groove.
The last bar is the full groove written as it should be. IT IS EXACTLY THE SAME as the previous two bars but is written condensed into one bar instead of two.
