The Music of the Ainur There was Eru, the One, who in Arda is called Il 鷙 atar。 and he made first the Ainur, the Holy Ones, that were the offspring of his thought, and they were with him before aught else was made. And he spoke to them, propounding to them themes of music。 and they sang before him, and he was glad. But for a long while they sang only each alone, or but few together, while the rest hearkened。 for each prehended only that part of me mind of Il 鷙 atar from which he came, and in the understanding of their brethren they grew but slowly. Yet ever as they listened they came to deeper understanding, and increased in unison and harmony. And it came to pass that Il 鷙 atar called together all the Ainur and declared to them a mighty theme, unfolding to them things greater and more wonderful than he had yet revealed。 and the glory of its beginning and the splendour of its end amazed the Ainur, so that they bowed before Il 鷙 atar and were silent. Then Il 鷙 atar said to them: 39。Of the theme that I have declared to you, I will now that ye make in harmony together a Great Music. And since I have kindled you with the Flame Imperishable, ye shall show forth your powers in adorning this theme, each with his own thoughts and devices, if he will. But I win sit and hearken, and be glad that through you great beauty has been wakened into song.39。 Then the voices of the Ainur, like unto harps and lutes, and pipes and trumpets, and viols and ans, and like unto countless choirs singing with words, began to fashion the theme of Il 鷙 atar to a great music。 and a sound arose of endless interchanging melodies woven in harmony that passed beyond hearing into the depths and into the heights, and the places of the dwelling of Il 鷙 atar were filled to overflowing, and the music and the echo of the music went out into the Void, and it was not void. Never since have the A inur made a ny music like to this music, though it has been said that a greater still shall be made before Il鷙 atar by the choirs of the Ainur and the Children of Il 鷙 atar after the end of days. Then the themes of Il鷙 atar shall be played aright, and ta ke Being in the moment of their utterance, for all shall then understand fully his intent in their part, and each shall know the prehension of eac h, and Il 鷙 atar shall give to their thoughts the secret fire, being well pleased. But now Il 鷙 atar sat and hearkened, and for a great while it seemed good to him, for in the music there were no flaws. But as the theme progressed, it came into the heart of Melkor to interweave matters of his own imagining that were not in accord with the theme of Il 鷙 atar, for he sought therein to increase the power and glory of the part assigned to himself. To Melkor among the A inur had be en given the greatest gifts of power and knowledge, and he had a share in all the gifts of his brethren. He had gone often alone into the void places seeking the I mperishable Flame。 for desire grew hot within him to br ing into Being things of his own, and it seemed to him that Il 鷙 atar took no thought for the Void, and he was impatient of its emptiness. Yet he found not the Fire, for it is w ith I l 鷙 atar. But being alone he had begun to conceive thoughts of his own unlike those of his brethren. Some of these thoughts he now wove into his music, and straightway discord arose about him, and many that sang nigh him grew despondent, and their thought was disturbed and their music faltered。 but some began to attune their music to his rather than to the thought w hich they had at first. Then the discord of Melkor spread ever wider, and the melodies which had been heard before foundered in a sea of turbulent sound. But Il 鷙 atar sat and hearkened until it seemed that about his throne there was a raging storm, as of dark waters that made war one upon another in an endless wrath that would not be assuaged. Then Il 鷙 atar arose, and the Ainur perceived that he smiled。 and he lifted up his left hand, and a new theme began amid the storm, like and yet unlike to the former theme, and it gathered power and had new beauty. But the discord of Melkor rose in uproar and contended with it, and again ther
