Two or more sharply contrasting rhythms that are performed at the same time interdependently.
Time signatures not containing a power of two in the bottom number.

Rhythms that divide the beat into a different number of equal subdivisions from that usually permitted by the time signature.
Drum fills that add or subtract a (partial) beat to create a meter shift, thereby achieving a wobbly sense of pulse.
Different changing time signatures at the beginning of each measure that create an irregular rhythmic feel.
Supplemental warmups for developing accuracy, fluidity, and rhythmic comprehension.
