Final answer:
The root sources for traditional black gospel music are African musical traditions, slave spirituals, and lined-out hymns.
Step-by-step explanation:
The possible root sources for traditional black gospel music are:
African musical traditions: The musical styles developed by blacks in the South were influenced by inherited musical traditions from Africa. This included an emphasis on percussion, syncopated rhythms, and bent or blue notes.
Slave spirituals: African American spirituals were influenced by the religious beliefs and Bible verses of enslaved individuals. They incorporated call-and-response forms, syncopated rhythms, and African-inspired body movements, such as hand-clapping and foot-stomping.
Lined-out hymns: Hymn singing traditions introduced by Baptist, Methodist, and Presbyterian missionaries in the South contributed to the development of traditional black gospel music.
African Americans created their own melodies and speech patterns when lining out hymns, effectively blackening what was originally a European form of music.
