The following exercises introduce hi-hat openings to different beats in the bar. The symbol "o" indicates that the hi-hat should be struck in a slightly open position on that particular beat.
The symbol "x" indicates the beat in which the hi-hat is closed. The effect of the resultant sound changes depending upon how far apart the two hi-hat symbols are when struck. Experiment for yourself to create a sound you like.
Try adding hi-hat openings to some of the patterns already covered.
