Without a doubt, African-American Spirituals are the most influential compositions in the history of American Art and popular music. From their influence on the 19th century songs of Stephen Foster and the like, to the explosion of Jazz, blues, and ultimately everything from Gershwin to Elvis to Motown, Madonna, and yes, even Justin Bieber. Originally the songs of slaves, this heartfelt music is rich with the full expression of human emotion. It was orally passed down through the years until the late 19th century, when composers like Harry T. Burleigh began to write it down and bring it into concert halls and churches. It continues to inspire and feed the hungry soul to this day.
