psalmista

Also known as hymn writer, hymn-writer, hymnist, hymnodist, hymnographer

A hymnwriter (or hymn writer, hymnist, hymnodist, hymnographer, etc.) is someone who writes the text, music, or both of hymns. The Christian tradition views the composition of hymns as dating 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.
