Final answer:

Step-by-step explanation:
The blues evolved out of various musical styles, including ballads, field hollers, and ring shouts, but not symphonies. Ballads are narrative songs, while field hollers and ring shouts are African American vocal and dance traditions.
Symphonies, on the other hand, are large-scale musical compositions typically performed by orchestras. The blues developed as a unique form of music, influenced by African American spirituals and the experiences of black communities in the United States.
