Traditional jazz, often referred to as Dixieland, originated in the early 20th century in New Orleans. It is characterized by a lively, upbeat style that features collective improvisation, where musicians play off each other in real-time. Instruments commonly used include the trumpet, trombone, clarinet, and a rhythm section of piano, banjo, and drums. This genre draws heavily from African American musical traditions, incorporating elements of blues and ragtime. Notable figures in traditional jazz include Louis Armstrong and Jelly Roll Morton, who helped popularize the style. Traditional jazz remains influential, shaping many modern jazz forms and continuing to be celebrated in festivals worldwide.
