This arrangement of the NICEA tune is a fully-developed 4-stanza arrangement. Piano will introduce a rich harmonic shift in the introduction, and the instruments will join with the voices after 6 bars. Instruments also will layer for the transition into stanza 2 and into the a capella section on stanza 3. After 14 measures of rest as the congregation sings the third stanza, the piano and instruments build for a glorious climax on a key change and into "Holy, holy, holy, all the saints adore Thee," on stanza 4. This particular arrangement is fully set on pointing toward the holiness of God, and is one that your instrumentalists and congregation will talk about later.
