The Lord of the Rings, I.3: Three is Company wrote:The singing drew nearer. One clear voice rose now above the others. It was singing in the fair elven-tongue, of which Frodo knew only a little, and the others knew nothing. Yet the sound blending with the melody seemed to shape itself in their thought into words which they only partly understood.
The Silmarillion, XIX: Of Beren and Lúthien wrote:There came a time near dawn on the eve of spring and Lúthien danced upon a green hill; and suddenly she began to sing. Keen, heart-piercing was her song as the song of the lark that rises from the gates of night and pours its voice among the dying stars, seeing the sun behind the walls of the world ...
The Silmarillion, XIX: Of Beren and Lúthien wrote:The song of Lúthien before Mandos was the song most fair that ever in words was woven, and the song most sorrowful that ever the world shall hear. Unchanged, imperishable, it is still sung in Valinor beyond the hearing of the world, and listening the Valar are grieved ... and Mandos was moved to pity, who never before was so moved, nor has been since.
