Dixieland jazz developed in New Orleans in the early twentieth century, built around collective improvisation, bright brass, clarinet and banjo over a steady two-beat rhythm. It became a shorthand for old-time American celebration, street parades and early jazz culture, and later found a second life in cartoons, films and online edits that borrow its cheerful, nostalgic feel.
