Silmarillion - Ainulindale

[Aiwendil]

It just struck me that this resembles the way Goldberry's voice is described in LotR.

This is interesting, and it reminds me of a little idea I have about Tom Bombadil and Goldberry. My personal "theory" concerning Tom Bombadil is that he is not an incarnate in the same sense as Elves and Men, but rather a part of Arda itself, an intrinsic part of the world just like the mountains, the rivers, and the land. And he (as well as Goldberry) is constantly singing. Could this be a kind of echo of the Music of the Ainur, much like that still heard in the sea?
