Step-by-step explanation:
For the UofSC Dance Concert performance titled "under", the second section of the dance likely showcased music that drew from the rich traditions of African American music, given the context provided. The style of music for this section may have featured elements typical of African American musical traditions, such as work songs and spiritual tunes that have a long folk history in the United States. These music styles were a product of African influences, which include an emphasis on percussion, syncopated rhythms, and bent or blue notes, which have given rise to genres like jazz, blues, and gospel.
Furthermore, considering the historical context of African American Steppin' and its origins, which can be traced back to gumboot dancing of South African miners, it's plausible that the performance also incorporated elements of Steppin'. These traditions share common roots in African rhythms and movements, reflecting a mixture of cultural expressions with historical significance.
