[Luthien_ Tinuviel]

Now, what interests me is exactly why he considered "cellar door" to be such an illustrious phrase. It does sound quite nice, but I think we must consider the accent he was accustomed to - "cellar door" sounds much better to me as an Englishman would say it than with American pronuciation!

But how did he choose the phrase as an example? I don't suppose we'll ever know, really... and it would be hard to think of a particularly beatiful-sounding word or combination off the top of one's head. Yet I still wonder if there's some sort of a history to his choice.
