The Swing Era
Swing music, or simply swing, is a form of jazz music that developed in the early 1930s and became a distinctive style by 1935 in the United States. Swing uses a strong rhythm section that includes double bass and drums as the anchor for lead instruments such as trumpets, trombones, and clarinets. The name of the style comes from the "swing feel" where the emphasis is on the off–beat or weaker pulse in the music.
