What do you call the music that was a blend of ragtime and blues in

The music style that emerged from merging ragtime and blues elements is known as "jazz." Early jazz music gained prominence during the late 19th and early 20th centuries in African-American communities within the United States, most notably in New Orleans. Jazz incorporates syncopated rhythms, polyrhythms, improvisations, and a distinctive use of harmony, creating a dynamic and expressive musical style that heavily influenced subsequent genres like swing, bebop, cool jazz, and beyond.
