Open and Closed Hi-hats
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. Experiment with different degrees of openness until you find the sound you like.
This fill-in features an open hi-hat on beat "4 +".
Rhythmic variations incorporating snare drum and or bass drum can be created using the rhythmic figure 
. The following examples feature such variations played with a sixteenth note hi-hat pattern.
Playing the same rhythmic variations with an eighth note hi-hat pattern requires greater co-ordination. If you’re having difficulty with the following examples, try practicing each two part co-ordination possibility first, e.g.:
1) hi-hat and snare.
2) hi-hat and kick.
3) Snare and kick.
1 bar snare and/or bass drum variations featuring the rhythmic figure and previously covered rhythmic figures.
These two bar patterns feature a fill in the second bar
