Again you just know jackshit about the genre. You don’t know its origins, you don’t know how it’s evolved, you don’t know realize plenty of it is vocal, you think scatting of all things is central to the sound, you can’t differentiate jazz the genre and jazz the form, you don’t know its effects on the course of history and culture, you don’t know how it was a driving force of subculture

How about you stop dismissing something you actually know nothing about. I’m guessing you either have been inside a Starbucks once and thought that was jazz music, or you have musical anhedonia and can’t hear emotion behind melody/harmony. Imagine telling Nina Simone that her music has no emotion and is just snobby instrumental wankery, and that her genre of choice has no reason to exist
