Spirituals is a genre of songs originating in the United States and created by African Americans. Spirituals were originally an oral tradition that imparted Christian values while also describing the hardships of slavery. Although spirituals were originally unaccompanied monophonic songs, they developed into harmonized choral arrangements.
