What are the characteristics of the music art of North American Indians?

The art of North American Indians has obvious primitive religious color and military life characteristics, as well as important factors of natural environment.

Music The music of Indians living on the prairie and plain is still in the simple period of the primary stage of music, which can be clearly felt from its rhythm. Generally speaking, songs can be divided into religious songs, poetic songs and high-pitched songs, with single drums (instruments made of rawhide with a diameter of 0.25mm to 0.5mm for solo and chorus), big drums and double-sided drums (for large-scale dance accompaniment) as the main accompaniment. In traditional festivals, when Indians meet their friends, they should sing "welcome songs". When you sing for bears, you should sing the religious song Song of Bears (bears are regarded as the strongest gods and the cutest animals). When people sing religious songs, they gather in a sacred hut made of branches to hold a banquet, sing all night and sacrifice dried meat pies and other food to bears. Grassland dance is a popular song (first sung by soldiers, and then evolved into a performer's tour); There are about 100 sticks and balls, which are the songs that people sing in the game and the most popular songs. The host of this game is often a witch doctor, elder or special group. Both men and women can participate, but women can only sing or watch. Game participants can be divided into two groups, 2 to 20 people, sitting or kneeling face to face. There are 10 baseballs standing between the two sides. One of them has two cylindrical bones in his hand (one of which has a black line, so he can't see it in his hand), and keeps turning around the other side, so that the other side can guess which hand has the grain of the black line, and the rest are combined. It's convenient to win a stick and two bones if you guess right; If the opponent can't guess (within a certain period of time), the player who holds the bone wins two sticks, and the game continues as usual until one side loses all the sticks. Different "Cudgel Songs" have different rhythms.
