Answer: Jazz started in the southern united states and spread north with the great migration
Step-by-step explanation:
In the 1920s a mass migration of African Americans from the south to the north occured. It was known as the Great Migration. The Southern states were difficult for African-American because their civil rights were denied. Many of them decided to migrate to the North trying to get a better life and they took their culture with them. This is why, even though Jazz music was originated in the South, it spread to tge North rapidly.
