Triplets, when used with the swing beat create interesting fills. Here are a few examples:
The swing beat may also be written using triplet cymbal patterns, e.g., notice the eighth note rest in the middle of the triplet group. This creates the "swing" feel.
The wire brushes are used when a quieter or more subtle rhythm is required. They would be used in a dance band for slow and medium tempo swing songs.
The right hand will be playing the same pattern as the swing beat in the jazz section, with the bass drum playing on the first and third beats, while the hi-hat is closing with the left foot on the second and fourth beats.
The left hand will be rotating the brush on the head of the snare drum in a oval shape, going from the outer edge to the center and back continuously. The brush should be in the center position with each beat.
If you cannot keep up the pace of rhythm with the left hand in faster tempos then just slow the left hand down so that you are rotating at half the speed before. The brush should now be in the center for 1 beat and then at the edge for the second beat, back to the center for the third beat and out to the edge for the fourth beat.
