You can see from the above patterns that Desity and Polymetric rhythms make a visual pattern. However, when visualized while listening, each different meter or density may occupy a separate area of dimensional space. Each pattern has a relationship to one or more separate patterns. Thus, they become a whole. Each interrelationship also occupies its own dimension. Each dimension relates to a separate aesthetic feeling, each excites and motivates patterns of neurons in the brain, patterns within patterns. The more dimensions, the more space one's mind has room to fly around in.

 

When putting different types of patterns in different orientations, much care must be taken so that the whole is clear and effective. The more different things the rhythm has, the more difficult it is to keep it from getting confusing.

 

Examples:

 

P=pressed bass

M=muff
