Read it through once

Would that the structure brave, the manifold music I build, Bidding my organ obey, calling its keys to their work, Claiming each slave of the sound, at a touch, as when Solomon willed Armies of angels that soar, legions of demons that lurk, Man, brute, reptile, fly,--alien of end and of aim, Adverse, each from the other heaven-high, hell-deep removed,-- Should rush into sight at once as he named the ineffable Name, And pile him a palace straight, to pleasure the princess he loved!
