Swing dance was originally a tap dance of cowboys in the western United States, which was popular in the 1920s and 1930s. During World War II, American soldiers brought swing dance to England. Due to the influence of the war, people's mood of "eating, drinking and having fun" is high, which leads to jive's development to the point of madness. Cowboy originated from African-American dance, which is a fast-paced and exhausting dance. World War II was spread by American sailors. The melody is cheerful and jumping, with a rhythm of 4/4 beats, 42 ~ 44 bars per minute, six beats and eight steps. It consists of basic dance steps such as stepping, merging, jumping and turning. The sole of the foot is required to step on the ground, and the waist and crotch are required to swing like a pendulum. It is characterized by agile dance steps, jumping, relaxed, enthusiastic and cheerful dance. Originated in the United States, it was originally a tap dance by cowboys in the western United States. The popularity of jazz in the 1950s accelerated and improved this dance, but it still maintained the vigorous, romantic and bold style of cowboys in the American West.
