"It could be said that church music is not performed at all, but is offered...For when the choir sings in worship, we are all in the choir. Not all in the congregation sing the anthem, but all are involved. All are connected in spirit if not in voice...That is and always has been the ultimate purpose of ecclesiastical music."
Psalm 33: 1-3 requires both excellence and novelty from musicians:

Psalm 144:9 "I will sing a new song to you, O God; upon a ten-stringed harp I will play to you"
Psalm 98 "Sing to the Lord a new song, for he has done marvelous things"
Revelantion 5:9 "They sing a new song before the throne and before the four living creatures and before the elders. No one could learn that song except the one hundred forty-four thousand who have been redeemed from the earth"
Psalm 100 (Ives) Jubilate "a celebration of joy, an exclamation of jubilant praise for our God who creates us, sustains us, and forgives us."
