Read it through once

But here is the finger of God, a flash of the will that can, Existent behind all laws: that made them, and, lo, they are! And I know not if, save in this, such gift be allowed to man, That out of three sounds he frame, not a fourth sound, but a star. Consider it well: each tone of our scale in itself is naught; It is everywhere in the world--loud, soft, and all is said: Give it to me to use! I mix it with two in my thought, And, there! Ye have heard and seen: consider and bow the head!
