All that jazz

Origin

As jazz music exploded onto the American scene in the early 20th century, its improvisational flair and energetic rhythms captivated and sometimes confounded audiences. The term 'jazz' itself became a vibrant shorthand for something new, exciting, and perhaps a bit overwhelming. From this cultural phenomenon, the phrase 'all that jazz' emerged as a convenient verbal flourish, a catch-all for the accompanying details, the related paraphernalia, or simply 'that sort of thing.' It evoked the all-encompassing nature of the music, allowing speakers to gesture towards a broader category of items or ideas without having to list them exhaustively.
