for SATB and piano or harp The King of Love My Shepherd Is sets Psalm 23 to an arrangement of the Irish traditional melody St. Columba. Rutter keeps the first three verses largely in unison, alternating between male and female voices, before allowing the music to bloom into rich and ever-expanding polyphony for the last three verses. The arpeggios in the accompaniment, distinctly Gaelic and gently scored, can be performed either on harp or piano.
