Jazz music originates from the black community of New Orleans during the 1900's. It didn't start gaining traction until the 1920's when Southern African Americans began to move to Chicago for work. Also, new technology, such as radios, helped popularize this genre. In fact, the 1920's is often referred to The Jazz Age due to the booming success of jazz during this period.
Jazz had a significant influence on fashion, dances, moral standards, youth culture, and even race relations. Due to the mass popularity of jazz, it was one of the first genres of African-American based music to be culturally appropriated by white Americans. This cultural appropriation furthered segregation as radio hosts began to only play jazz from white musicians. Although the radio helped popularize this genre, it discredited the origins of jazz.
However, Louis Armstrong, one of the most famous jazz musician from New Orleans, broke these racial barriers. He played in many mixed clubs and even in white only clubs. In this way, he was one of the first to introduce integrated music. His music also revolutionized the way jazz was performed as he introduced the extended solo.
