The Swing Era refers to a period in American music from the late 1920s to the mid-1940s, characterized by the popularity of swing jazz. This style featured big bands, which typically included brass, woodwinds, and rhythm sections, creating a lively and danceable sound. Notable musicians of this era included Duke Ellington, Count Basie, and Benny Goodman, who helped popularize swing music across the United States. During the Swing Era, dance halls and ballrooms flourished, with people flocking to hear live performances. The music was often associated with social dancing, particularly the Lindy Hop and Jitterbug. The era came to a decline with the onset of World War II and the rise of other musical styles, but its influence remains significant in jazz and popular music today.
