Sachs also borrowed the words of Fritz Bermer and pointed out that "the relationship between dance and decoration is very attractive. These two forms are almost entirely spontaneous-decoration is more spontaneous than any other plastic arts. Because their production is stimulated by specific actions, they will inevitably show various forms associated with actions. " Sachs provided many examples for this: "Australians like to organize Z-shaped groups; Melanesians divides the space into two equal halves with a vertical midline in most devices; Micronesia likes to decorate the edges and leave the inner layer blank; Samoans like to divide the space evenly into chessboards. This arrangement of Samoans gives people a quiet impression; In sharp contrast to melanesians's fast linear queue. The latter is undoubtedly a regular structure, showing internal tension and momentum. Those who feel this difference must see the different temperament that determines their dance forms: the extremely stiff temperament of Samoans sitting on the spot, and the vigorous temperament of melanesians in the dance. They will also feel that there is a spiritual connection between the restless Z-shaped queues of Australians and the columns of the Koropolis. " Of course, Sachs has realized: "The development process of dance forms has been condensed into a state of coexistence of various forms." . We find that some ethnic groups … acknowledge their relationship with society in the form of ring dance; Show traces of his personal characteristics in the form of solo dance; It is expressed in a gentle, obedient and natural form of wisdom, dignity and eccentricity, in a warm and humorous way and in an endless observation of everything in the world and beyond everything.
