Which Native peoples influenced southern-style powwow music and dance?

"Southern-style" powwow music and dance have their origins in the central and western regions of Oklahoma and are rooted in the cultures of the southern Plains tribes. The Native peoples who primarily influenced these styles include the Kiowa, Comanche, Pawnee, and Ponca peoples.1

In the southern tradition, singing is characterized by a lower vocal range compared to northern styles, and the music features three accented drumbeats between the repetitions of each verse. Furthermore, drumming in the southern style is considered an exclusively male activity, where men play the drum while singing, and women sing while standing in a circle around them. Specific dance forms associated with this style include the men’s southern straight dance and the women’s southern cloth dance.1
