Final answer:
The music of Dvořák is most strongly inspired by African American spirituals.
Step-by-step explanation:
The music of Dvořák is most strongly inspired by African American spirituals. African American spiritual songs have a long folk history in the United States, and they influenced the musical styles of Dvořák and other composers. The spirituals' African influences can be heard in the call-and-response form, syncopated rhythms, and the use of "blue" notes.
