Sacred Harp: Sacred Harp singing is a tradition of sacred choral music that originated in the American South of the United States.  The name is derived from "The Sacred Harp," a ubiquitous and historically important tunebook printed in shape notes.  The work was first published in 1844 and has reappeared in multiple editions ever since.  Sacred Harp music represents one branch of an older tradition of American music that developed over the period 1770 to 1820 from roots in New England, with a significant, related development under the influence of "revival" services around the 1840s.  This music was included in, and became profoundly associated with, books using the shape note style of notation popular in America in the 18th and early 19th centuries.
