10/05/04. edited 02/10/08: The Golden Spiral or Golden Mean or PHI (1.618...) is a decimal approximation* to the ratio of the Fibonacci Series expressed in Whole Numbers. In order of increasing decimal equivalent value, as shown below, the music interval equivalent oscillates between Minor and Major Sixths. As the PHI ratio decreases a musical interval of Enharmonic Sixths is approached save there is no Enharmonic Sixths in standard music and as such cannot actually be reached any more than the approximation can resolve itself. PHI is an irrational number just as PI is irrational; i.e., a reduced ratio of two unlike entities. Which is to say should never be reduced because to do so is dividing apples by oranges - a straight line (diameter) is not the same as a curved line (circumference). The same principle applies to PHI whole number ratios being composed of two distinct entites; i.e., a lower quantity and a higher quantity. I admit this sounds trivial but it is not as nature does not admit to a 0.9 pregnancy. Please review Hull's "Quadrature of the Circle"** wherein he reviews Parker's original squaring of the circle by NOT dividing unlike terms such as triangles, squares, circles and components thereof such as straight and curved lines.

RATIO DECIMAL APPROXIMATION
1:1 = 1 = Unison
2:3 = 1.5 = Perfect Fifth
5:8 = 1.6 = Minor Sixths
13:21 = 1.61538... = Minor Sixths
°:° = ° = Enharmonic Sixths
21:34 = 1.61904... = Major Sixths
8:13 = 1.625 = Major Sixths
3:5 = 1.6667 = Major Sixths
1:2 = 2 = Octave


Nature, especially music, works on a natural basis. The human tendency to "round off" is never found in nature. The (in)human decimal (Metric) system has naught to do with naturally occuring phenomena which seems to prefer whole number ratios and proportions whether base 3, 5, 7 or 12 or other.

*APPROXIMATION: "something that is approximate especially : a mathematical quantity that is close in value to but not the same as a desired quantity" [Merriam-Webster]
