Swing originated in the United States in the 1930s as a jazz style known for its variety of instruments. It was the most popular music of the decade, typically featuring a piano, cello, drums, and trumpets. Swing also refers to a dance that emerged in the southern US in the early 20th century, where dancers improvised moves to piano music. The African American community was primarily responsible for developing swing dance. Traditional swing clothing included dresses for women, shirts with suspenders and trousers for men, and special shoes with flexible soles for both.
