Step-by-step explanation:
The cultural context for the evolution of brass bands in the U.S. is rooted in the rich tapestry of American social and musical heritage. In the United States, the development of brass bands can be traced back to various influences, including African rhythms and European military band traditions. Work songs, spiritual tunes by slaves, and free blacks in the South have a long folk history in the United States, playing a crucial role in shaping American musical styles such as jazz, blues, and gospel. The presence of brass bands became a defining feature of the sociocultural environment during the turn of the century.
In urban America, as cities grew due to immigration and migration, so too did the cultural activities that residents enjoyed. New forms of music, such as ragtime, started to become part of the urban landscape, influenced by the different ethnicities and local conditions of the time. Brass bands, often associated with sporting events and public celebrations, became popular as they provided a sense of community and shared cultural identity among Americans. They also offered a form of entertainment and a means of expression for both the musicians and their audiences, reflecting the social changes and movements of their era.
