"Third Octave is Golden." Keely

"This belief in perfect geometry, natural order and predictability was central to the Pythagorean worldview, as it had been to civilizations long before the Greeks. So when it was discovered that a stack of five perfect 5ths does not close to form a regular pentagram at the third octave as expected – forming instead an open and warped pentagonal shape in logarithmic pitch space – this was taken as a profound error in nature.

"What Pythagoras found during his musical experiments was the last interval must be stretched up by a messy ratio of 128:81 (instead of the perfect 5th ratio of 3:2) to align with the third octave. In music lingo, the last interval must become an augmented 5th instead of a perfect 5th.5 While very close to creating a pentagram, it still fell short of the perfection expected.

"This imperfection is central to understanding the Greek worldview because it reveals a conflict, a paradox really, between the cyclic geometry of a regular pentagram and the Spiral of 5ths as it occurs naturally in sound. Philolaus (c470 BC – c385 BC), a “most ancient” follower of Pythagoras, referred to this paradox in the opening of his book Peri physeos, or On Nature:

“Nature in the cosmos is composed of a harmonia between the unlimited and the limited and so too is the whole cosmos and everything in it.

"This gap between the closed or “limited” octave cycle and the infinite or “unlimited” spiral of pitch was a major embarrassment to the Pythagoreans because it undermined the purity of their philosophy of numbers and simple proportions. Given the importance placed on numeric proportions by the Pythagoreans, we have to wonder how they might have reconciled this error within their belief system.

"With many early Pythagorean treatises lost or stolen, we are left with only the accounts of later Greek philosophers such as Philolaus, Nicomachus and Plato. From these accounts we know about Pythagoras’ theories of numerical proportion, his tuning methods, the Greek modes and the supreme importance of his adopted symbol the pentagram.

"As for the pentagram, Pythagoras appears to have first learned of it from his closest teacher, Pherekydes of Syros, who wrote a treatise entitled Pentemychos describing what he called the “five hidden cavities” of the soul. Of course, the notion that a geometrical shape could somehow be related to our “soul” sounds very mystical and unscientific to modern ears, but he was essentially correct about the pentagram playing a very important role in how nature organizes itself.

"Beyond the obvious organizing principle of the number 5 in such things as roses, starfish and the human anatomy, the pentagram contains a very special numerical proportion known as the “golden ratio.” If you have not heard of it before, the golden ratio is an infinite non-repeating proportion of about 1 to 0.6 usually represented by the Greek symbol Phi or “Φ” (pronounced either “fi” or “phee”). The most important thing about this ratio is that it is found approximated everywhere in nature" INTERFERENCE - A Grand Scientific Musical Theory, Richard Merrick, 2011, Third Edition
