What is considered to be the only original American cultural art form?

Jazz is widely regarded as the only original American cultural art form. It evolved from the fusion of African-American musical traditions and European influences during the late 19th and early 20th centuries, particularly in New Orleans, Louisiana. Jazz is characterized by its improvisational nature, syncopated rhythms, intricate melodies, and unique harmonic structures. It has spread worldwide and become an influential force in modern music.
