Commissioned for the American Guild of Organists 2014 National Convention in Boston, Mass., Eternal Ruler of the ceaseless round is a joyful and exuberant setting of the well-known hymn by John Chadwick. It begins with a rich organ introduction before the choir (and congregation) join in with a unison presentation of the melody. The second section explores the Lydian mode, with its rising fourth, while the adamantine final verse brings the anthem to a resolute close that reflects the text's profound depiction of unity and human understanding.
