Final answer:
Louis Armstrong moved to New York City in 1924 to be part of Fletcher Henderson's band, contributing greatly to the jazz scene during the Harlem Renaissance.
Step-by-step explanation:
In 1924, the influential musician Louis Armstrong moved to New York City to join Fletcher Henderson's dance band, where he would become a central figure in the development of Jazz during the Harlem Renaissance. Harlem, a vibrant African American community in New York, was a hub for the jazz movement, drawing artistic talent from across the United States.
It served as a melting pot where musical styles such as the Chicago style of Louis Armstrong, the St. Louis Blues, and Charlie “Bird” Parker's Kansas City Jazz came together, creating a rich and innovative musical landscape.
Armstrong's arrival in Harlem during the 1920s was part of a larger historical context known as The Great Migration, wherein a significant number of African Americans moved from the South to northern cities, seeking better economic opportunities and artistic freedom. This socio-cultural movement helped form a burgeoning middle class and fostered an environment where Armstrong and other artists could flourish and have a profound influence on the course of music into the 21st century.
