Disclaimer: Tolkien created those Falls... Kortirion created this thought.
Falls of water are as individual as women’s voices. In my childhood Rivendell, they sang in chorus, each adding a different note to my night-time lullaby. In the mountains, often a lone stream falls with the spattering keening of a solitary balladeer, of spring-melt defiance, summer-heat welcome, and in winter... icy lament. Lothlorien’s serene cascades sing plaintive tales of times past, repeated until the stones have hollowed beneath them.
But at Rauros... the mighty Anduin thunders its challenge to the North:
‘No further... the rest is Gondor’s!’
Its voice blares like trumpets... but to me... those falls will always weep.
