The original Southern FOLK music was here long before any foreigners came to the South. Native American tribes like the Cherokees, Creeks, Seminoles, and Choctaws were producing their music with drums, rattles, flutes, etc. using their five note compositions.
Next came groups from Spain, France, Germany, England, Ireland, Scotland, etc. bringing their forms of music:
Cotillion which became square dancing
Black cakewalk originating from Anglo-Saxon formal dancing
Virginia reel coming from a variation of the upper-class Sir Roger de Coverley dance
Appalachian fiddle tunes
Opera with first opera ever performed in America at Charleston, SC
