Their father, Levi Philip Denson, was a Scots-Irish farmer, Methodist minister, and Sacred Harp singer; their great-uncle James Denson composed a Christmas anthem for the first Sacred Harp songbook, compiled and published in 1844 by Benjamin Franklin White of Hamilton, Georgia. Their mother, Julia Ann Jones, was also musical and from a musical family. Seaborn and Thomas Denson and their siblings grew up on a farm that included a working gold mine, a relic of thousands in the area that were active between 1836 and 1849. As children, the boys worked on the farm, panned gold, and attended their father's Methodist church, local schools, and singing schools. They married Sidney and Amanda Burdette, respectively, who were sisters from a Sacred Harp family in nearby Georgia. Together, they all sang at home and played secular music on the harmonium, cornet, banjo, and mandolin.

In 1920, at a Winston County sing, the Densons met Vanderbilt University professor George Pullen Jackson, who was beginning to research southern traditional music and later published two seminal works on Sacred Harp and other southern traditional music. In the 1930s, he introduced the Densons to John and Alan Lomax, academically trained researchers of traditional folk music. In 1933 Thomas Denson established the Sacred Harp Publishing Company, which bought the rights to the 1911 Original Sacred Harp songbook, the standard collection upon which most modern revisions are based, and the brothers began the new edition. Unfortunately this task went uncompleted before their deaths: Thomas's on September 14, 1935, and Seaborn's in on March 18,1936.
