A hymnwriter (or hymn writer, hymnist, hymnodist, hymnographer, etc.) is someone who writes the text, music, or both of hymns. In the Judeo-Christian tradition, the composition of hymns dates back to before the time of David, who is traditionally believed to have composed many of the Psalms. The term hymnodist, in the United States more than in other regions, broadens the scope to include the study of hymns. Source: Wikipedia (en)
