The kind of music, song, and dance a people generates, with its characteristic rhythm and beat, forms one of the best indexes of its cultural style, and in America, the dominant musical styles are blues, swing and jazz. The lyrics to this music are often foolishly sentimental and sometimes non-sensical, but frequently they embody a wild and earthy humor, or a sad and tragic strain. As distinguished from most American popular tunes, American hot music is not written to be danced to. Yet there is an internal beat in jazz which relates deeply to dance: the movements of the body interpret the music´s intent better than words can. When there is dancing, however, the dances break away from a formal pattern and, at their bat, keep with the improvisation (即興) of the music. Unlike earlier American folk dances, which are collective, so-called ballroom dancing is performed by couples. Each couple is comparatively alone, not being well enough acquainted with the other couples on the dance floor to join them. But, in the swing dancing, as the music mounts the partners separate to execute complicated solo variations and then rejoin each other. As the music approaches one of its climaxes, the dancers pay the musicians the tribute(贊美) of gathering around to cheer them on. In popular dance and music, Americans come closer to reaching a native idiom of religious feeling than they do in any other aspect of their lives.
