spiritual

"of or concerning the spirit" (especially in religious aspects), c.1300, from Old French spirituel (12c.), from Latin spiritualis, from spiritus "of breathing, of the spirit" (see spirit (n.)). Meaning "of or concerning the church" is attested from mid-14c. The noun sense of "African-American religious song" first recorded 1866.

Religious songs of African-Americans, often written with freer rhythms and harmonies than most standard hymns. Spirituals, many of which go back to the days of slavery, often speak of biblical models of deliverance, like the Exodus. Some well-known spirituals are “Gonna Lay Down My Burden,” “Joshua Fit the Battle of Jericho,” “Nobody Knows the Trouble I've Seen,” “Swing Low, Sweet Chariot,” and “When the Saints Go Marching In.”
