O.G.//It can not embody ideas as that would imply creation by an intelligence that had ideas.//
Consider, for example, the work of Pythagoras on the relationship between sound and mathematics, observing the length of a vibrating string and our perception of its tone. He discovered that two identical strings
(say, 2 guitars today) at similar tension make tones that sound 'good' together, exactly when the lengths of the strings are in ratios of small or whole numbers.
So. for example, when the ratio of lengths is 1:2, the tones form an octave. When the ratio is 2:3 we hear the dominant fifth; when the ratio is 3:4, the major fourth. In musical notation (in the key of C) these correspond to playing two Cs, one above the other, together a C-G or C-F, respectively.
These tones which sound good together we say are in 'harmony' and are the basic building blocks of classical music and of most folk, pop and rock. Why should we find these tone combinations, with their undoubted reliance on mathematics and the world of numbers, so appealing?
