The Union Harmony is a shape note hymn and tune book compiled by William Caldwell.
William's children include Tillman A., Orville H., Cordula J., Leonidas Beecher, Eliza, Catherine Josephine, Mary Alice, Evaline V., and Amy H. Caldwell.
Union Harmony or Family Musician was a four shape tunebook, registered in 1834, but printed in 1837 in Maryville, Tennessee by Ferdinand A. Parham.
Writers from George Pullen Jackson to Harry Eskew consider the chief contribution on Caldwell and the Union Harmony to be the preservation of folk songs of the oral tradition.
