The first is the Chant setting. Since I don't yet have software for chant notation, I had to go into my regular music software, which can do shape notes, and eliminate stems, but I get a five-line staff. So, I had to go to the basic "Paint" tool (thank God I can also save as a .tif), eliminate the fifth line, then draw the chant clef. It's obviously not a Liber Usualis quality layout, but it's ok for now.
Second is a more modern metrical setting found in many hymnals, including the St. Gregory Hymnal and Catholic Choir Book.
Third is my own setting, written in the fall of 1999, while serving at Holy Name of Jesus Church in Providence. In an attempt to return this antiphon into the Post-Conciliar Church in North America, I added versicles to Psalm 93 (92), in Latin. This is the setting we'll be using at Holy Ghost Church for the Solemnity of Christ the King.
