Both use drums in their music. Notice how the drums affect the way the dancers move. Polyrhythms are two or more rhythms happening at once. As you listen to the drums, see if you can hear more than one rhythm at a time. Watch the dancers and watch how their bodies respond to the many rhythms.
Footwork is another way to highlight rhythm in dance.
You will see the fancy and complicated patterns of the Mexican dancers. Notice how they hold the rest of their body. Complicated patterns of the heel, toe and whole foot create sound patterns that are like a drum beat. For example, in some Balinese dance styles, a changing movement dynamic that switch from slow to quick and back again is considered a desireable flow of events. Mexican music often has a strong, regular rhythm indicated in the music.
