Of course the SCOTCH-IRISH were not the only source of BALLADS. In the Southwest the SPANISH and MEXICANS influenced these BALLADS leading to TEX-MEX. The French with their influence in Louisiana bayous gave us ZYDECO and CAJUN music.
The slaves brought from Africa gave us BLACK GOSPEL after their conversion to Christianity and also the BLUES. They also gave us the BANJAR which became the BANJO used in BLUEGRASS and COUNTRY and later VAUDEVILLE.
With America becoming a “melting pot” every nationality that came here brought their BALLADS, FOLK SONGS and favorite musical instruments.
