saxophone still put forward the conclusion that "the whole dance may originate from the embryo of rhythm structure". He pointed out: "The first tool to beat the beat was the feet that knocked down the ground-sometimes elbows and knees were also used for this job. In order to modify the monotonous stomping sound, people beat other parts of their bodies with their hands to make a louder sound. In this way, the upper arm, waist, abdomen, buttocks and thighs all become batters. " Later, around the end of the Paleolithic Age, "dancers not only beat their bodies, but also beat aprons or folded animal skins;" They hit the ground with sticks and often build foundations that echo more than bare ground; They sometimes wear ornaments that can make noise on their bodies. When such ornaments are tied to their knees, calves or ankles, stamping their feet will produce better sound effects. If you use a stick instead of your feet, you can also tie the jingling ornaments to the stick. "
