ANCIENT CHINA<br />

Continued from preceding page<br />

before vanishing into final silence.<br />

Here was indeed a high- precision<br />

science and craftsmanship justly corn -<br />

parable to the most refined modern<br />

techniques in optics or electronics.<br />

Many of the large pentagonal stones<br />

Discussed above had arched hases for<br />

improving tone duration and sonority.<br />

It was found that the diameter of<br />

the curvatures was the same for several<br />

stones in the same set, suggesting that<br />

they were parts of, and cut from, one<br />

ring -shaped original unit. A study<br />

extending over three years finally<br />

showed that the ancient acoustical engineers<br />

and mathematicians had devised<br />

a system of cutting two very<br />

large circular stone disks (of the Pi<br />

type ) into six segments each, forming<br />

six tones each of the twelve semitones<br />

contained in the octave. According to<br />

Chinese cosmological tradition, there<br />

are six male and six female tones in the<br />

twelve -tone system. They follow each<br />

other alternatingly in the construction<br />

of the circle of the fifths.2 The six<br />

male tones came from one large ring,<br />

the six females from a second slightly<br />

smaller unit, and they were cut up<br />

according to a secret mathematical<br />

division, without leaving scrap or<br />

fragments from the ring's total circumference.<br />

Thus, the cosmological unity<br />

of the tone system and its derivation<br />

from two co -equal male and female<br />

elements were actually built into the<br />

stones. This mathematical secret has<br />

been lost, and so far nobody has been<br />

able to reconstruct it, in spite of all<br />

our advanced mathematical knowledge<br />

and computing equipment. It reminds<br />

one of the case of the Cremona violin<br />

makers; no amount of modern research<br />

can produce anything even<br />

remotely comparable to the masterpieces<br />

of a Stradivarius or Guarneri.<br />

These are some of the focal points of<br />

ancient Chinese achievement that justify<br />

-- to me, anyway - the contention<br />

that we have something to learn<br />

from them. The Chinese did things<br />

the hard way. Our easier ways may<br />

have hazards. The senses of modern<br />

researchers and engineers have become<br />

blunt and unresponsive, because they<br />

rely completely on testing and measuring<br />

instruments. The Chinese had<br />

to train themselves throughout many<br />

centuries to develop an incredible<br />

!C was male. G female, D was male, A was female, etc.<br />
