But he does NOT mention that this can ONLY be derived from noncommutative phase!! Oops.
When you play the Perfect Fourth as 4:3 you are neglecting to mention that the Lower Frequency was derived from Noncommutative Phase of doubling the 2/3 as the Undertone of the 1:1 fundamental frequency ratio. See Professor Richard McKirahan's translation of Philolaus for details - the first Greek use of irrational magnitude math was from Philolaus. So you say the ratio is 4:3 but as an Overtone harmonic that is NOT the lower note in the scale. It is the 4:3 as G to C and so would have to be a perfect fifth to the octave higher. See Alain Connes, Fields Medal math professor talk on quantum music of the sphere as cited by Math PRofessor Micho Durdevich for details - as I quote Durdevich:
"However, even in this case there is a highly non-commutative world of higher order collectivity algebras B(n). This can be used to capture the geometry of rotations, like those appearing in the classical Pythagorean octave versus perfect fifth considerations."
"the Pythagorean music school was rapidly able to calculate the tone fa-sol as the difference between the fifth do - sol and the fourth do - fa, and consequently as the ratio 3/2 : 4/3 = 9/8 [logarithm]....The Pythagorean tradition denied that it was possible to divide the tone into two equal parts (semitones [based on rational ratios])....Dividing the Pythagorean tone into two parts would mean admitting the existence of the proportional mean between 9 and 8, that is to say, 9 : [a] = [a] : 8, where 9:[a] and [a]:8 are the proportions of the required semitone....Clearly [a]= [square root of 9 x 8] and therefore [a] = (3 x 2) x [square root of 2]!"
Math Professor Tito M. Tonietti, University of Pisa, Italy and
"However, he [Archytas] noted that the product of the arithmetic mean and the harmonic mean is equal to the square of the geometric mean, so this gave a way of dividing the fifth of 3:2 into the product of 5:4 and 6:5."

" no matter how high one goes in the harmonic series, a fundamental pitch will not produce a perfect fourth above the fundamental. ..Just as Slonimsky opined, the perfect fourth above the tonic is nowhere to be found. ... Thus the perfect fourth above the tonic enters the scene, not as part of a stable major scale, but as a tempter, a seducer, a built-in modulation away from the true tonic. The perfect fourth, and not the tritone, is the true “devil in music.” It’s no “subdominant.” It’s the phantom tonic."
