One of the coolest articles on sound and vibration I can recall having read

Leaving the concept of deity aside as a factor, a most interesting article. I wish I could follow the math better but the commonality of recurring fifths throughout, down from a fractal level and up to a galactic one, reminds me of a giant clock, orderly to a unprecedented degree, and we are all a part/product of it due to it's design and influence, which would explain how we compose music and the satisfaction we derive from it. We're repeating and reinforcing what is, down to a molecular level, ourselves.

Or something like that. :-)

All the best,
