Swing is the jazz style that emerged during the early 1930s and emphasized big bands. It spilled into the late 1940s and then remained popular in recordings, film, and television music long after its main proponents had disbanded. Most swing-style groups had at least 10 musicians and featured at least three or four saxophones, two or three trumpets, two or three trombones, piano, guitar, bass violin, and drums. Guitarists, bassists and drummers offered repeating rhythms that were sufficiently simple, buoyant, and lilting to inspire social dancers, the style's largest audience. Musicians strove for large, rich tone qualities on their instruments.
