Black people have a strong passion, impulse and rhythm for life; Rhythm is the core of black traditional music, and the passion and impulse in life are bred in it. The rhythm of Africa is free and unrestrained, full of rhythm and passion. In Africa, there is a strong sense of music rhythm in many labor scenes, such as rowing people singing with the movement of rowing, porters singing while walking, and housewives singing while spring rice. French missionary E· A· Casari (1812 ~ 1891) described the Soto people in southern Africa as follows: Soto people especially like the rhythm in music, and the stronger the rhythm, the more they like it. Women wear metal rings that ring whenever they move. "They often get together to grind their own wheat with their hands and sing songs with the regular movement of their arms, which are very harmonious with the rhythmic sound of their rings." When dancing, Soto people beat time with their hands and feet, and hung some special bells on their bodies to enhance the rhythm of music. Hottentots has a strong sense of rhythm even when singing lullabies, love songs and sacrificial carols. Seeking a strong and unrestrained rhythm is the basic characteristic of African traditional music culture. In addition, African black music is closely related to dance, and its main rhythm is also from the rhythm of dance movements. And the rhythm is very complicated. The performer deviated from the main rhythm from beginning to end and made various variations on the melody. There are two or several independent rhythmic voices. This rhythm is the rhythm of life, full of tenacious motivation and enthusiasm.
