When I wrote a post about the Biblical sources of "Go Tell It on the Mountain" shortly before Christmas a little over year ago, I noticed a small feature about the tune, titled simply "Go Tell It." The first two lines of the refrain ("Go tell it on the mountain, / Over the hills and ev'rywhere") are sung to these musical phrases:
"Ev'rywhere" is sung with a melisma (B A B A G), which - to some degree - musically illustrates the breadth to which the good news "That Jesus Christ is born" should be spread.
