"Wave after wave, each mightier than the last,
Till last, a ninth one, gathering half the deep
And full of voices, slowly rose and plunged
Roaring, and all the wave was in a flame"

-- Alfred Lord Tennyson

Ivan Aivazovsky's painting "The Ninth Wave" has been called "The most beautiful painting in Russia":

It's a theme that interested Kate Bush too. Here is a lovely calming tune for a Sunday morning from the start of her Ninth Wave "And Dream Of Sheep" (ignore the video, it's just a load of pictures of her):

Cheers, Tom.
