Accents can often be created simply by using different parts of the drumkit. The most common example of this is the use of the crash cymbal. If you play a groove using the hi hat and then play the crash cymbal it automatically gives the effect of an accent even if you don’t hit it any harder.
Another common situation where this occurs is in playing a fill. If you play part of a fill on one drum (e.g., snare) and another part of the fill on a different drum (e.g., tom), the difference in tone and the surfaces of the drums will create accents as demonstrated in the following example.
