The Return of the King
Merry looked out in wonder upon this strange country, of which he had heard many tales upon their long road. It was a skyless world, in which his eye, through dim gulfs of shadowy air, saw only ever-mounting slopes, great walls of stone behind great walls, and frowning precipices wreathed with mist. He sat for a moment half-dreaming, listening to the noise of water, the whisper of dark trees, the crack of stone, and the vast waiting silence that brooded behind all sound. He loved mountains, or he had loved the thought of them marching on the edge of stories brought from far away; but now he was borne down by the insupportable weight of Middle-earth. He longed to shut out the immensity in a quiet room by a fire. (5.3.4)
On down the grey road they went beside the Snowbourn rushing on its stones; through the hamlets of Underharrow and Upbourn, where many sad faces of women looked out from dark doors; and so without horn or harp or music of men's voices the great ride into the East began with which the songs of Rohan were busy for many long lives of men hereafter. (5.3.95)
"And why should such songs be unfit for my halls, or for such hours as these? We who have lived long under the Shadow may surely listen to echoes from a land untroubled by it? Then we may feel that our vigil was not fruitless, though it may have been thankless."
Pippin's heart sank. He did not relish the idea of singing any song of the Shire to the Lord of Minas Tirith, certainly not the comic ones that he knew best; they were too, well, rustic for such an occasion. (5.4.15-6)
