What do you mean by cheerful music and black dance in the ballroom? I heard these two words, but I don't know what they mean.

In ballroom culture, "bright songs" usually refer to lively songs, usually pop songs or dance music, which are suitable for dancing and entertainment. "Black Dance" is a dance form, which originated from African-American culture. It is a dance style based on rhythm and rhythm, and usually includes hip-hop, break dance, lock dance and other dance elements.

"Black Dance" is usually performed with slow pop songs or rhythmic music, emphasizing the skills, strength and expressiveness of dancers. In contrast, Bright Song pays more attention to cheerful atmosphere and entertainment. In ballroom culture, "black dance" and "bright song" are usually performed separately, but some dancers will perform different dance styles in the same song.
