The lasting popularity of the Sacred Harp can partly be attributed to the strong support of singing conventions like the Chattahoochee Musical Convention.  The group was established by B.F. White, and in 1904, the members pledged to use no other book but the Sacred Harp for their singings.  This image shows the convention gathered at the State University of West Georgia in 1956, two years after its move to the location.
