The Law of Pipes
In olden times Huang-ti ordered Ling Lun to establish the lü. Ling Lun travelled from the western to the shady northern side of Mount Yuan Yü. He selected bamboo grown in the Chieh Ch'i valley. He chose only a piece which was hollow and of even thickness. He cut off its knots and used the hollow section between the two joints, the length of which was 3.9 ts'un. And he blew the pipe and produced the sound kung of huang-chung. He then brought twelve other pipes of different lengths down from the mountain and he listened to the sounds of the male and female Phoenix birds. He grouped their sounds into the twelve lü. There were six sounds of the male bird, and another six of the female. He related them to the kung of the huang-chung and found that the huang-chung was the foundation of the lü-lü. [as quoted in "Myth and Reality in the Theory of Chinese Tonal System," by János Kárpáti -- Studia Musicologica Academiae Scientiarum Hungaricae, T. 22, Fasc. 1/4. (1980), pp. 5-14.
In order to understand the above passage, it is necessary, first of all, to realize that the syllable lü has different meanings, marked by different written characters, depending on the pitch with which it is spoken. Two of these meanings are: “law” and “pipe.” Thus, the well-known Chinese myth of the Yellow Bell (huang-chung) is based on either an amusing pun or a hilarious misunderstanding. The Yellow Emporer, Huang-ti ordered Ling Lun to establish the law but what he actually comes up with is a pipe. Which suggests that the person credited with determining the tunings which were to become the basis of the Chinese tonal system was tone-deaf.
This disconcerting notion is made more probable when we consult another version of the story, as told by the 1st Century BC historian Ssii-ma Ch'ien:
Starting from the first pipe, the author says, you construct a series of pipes either by "taking away or adding a third" from the pipes that follow. So if the length of the first pipe is 1, the next one is a third shorter, i.e. two-thirds its length, and the following one is a third longer than the previous one, that is 4/3, which will be 8/9 of the first pipe's length. (Ibid. pp. 6-7)
In other words, the tunings determining the lü-lü (literally “pipe-law”) can be constructed purely on the basis of measurement, with no need for any pitch awareness whatsoever. The first five pipes constructed from this method will produce the first five pitches of the “circle of fifths” (e.g., C – G – D – A – E), from which the familiar pentatonic scale can be derived: C-D-E-G-A, or, to use the Chinese terminology: kung, shang, chiao, chih, yü (equivalent to our do, re, me, sol, la).
But there is more. Thanks, possibly, to the aforementioned confusion over the meanings of lü, the Yellow Bell
was conceived simultaneously as a sacred eternal principle, the basis of the state and a note of definite pitch in music. . . It was considered important to find the correct pitch for each dynasty, or political disorder would be likely to ensue. (Peter Crossley-Holland, as quoted in Phillip Tagg, A Short Prehistory of Western Music (rough version 1), p. 15.)
Moreover, possibly because a “law” can also be understood as a “rule,” which can be extended to mean “standard of measurement” (as for example a “ruler”),
The choice of the primary pitch in China had extramusical as well as practical applications, for the length of the yellow bell pipe became the standard measure (like a metre); and the number of grains of rice that would fill it were used for a weight measure. Thus, the pipe itself was often the property not of the Imperial music department but of the office of weights and measurements. (Encyclopedia Britannica website, East Asian Arts.)
And since a “ruler” is not only an implement that measures according to a “rule,” but the one who makes the “rules” (in the sense of “laws”) the Yellow Bell took on central importance in Chinese civilization, putting music “in tune with the universe.”
"Music is the harmony of heaven and earth while rites are the measurement of heaven and earth. Through harmony all things are made known, through measure all things are properly classified. Music comes from heaven, rites are shaped by earthly designs." (Ibid.)
[T]he five fundamental tones are sometimes connected with the five directions or the five elements, while the 12 tones are connected by some writers with the months of the year, hours of the day, or phases of the moon. The 12 tones also can be found placed in two sets of 6 on Imperial panpipes (pai-hsiao) in keeping with the female-male (yin-yang) principle of Chinese metaphysics. (Ibid.)
Origins
There are several things that interest me in this remarkable myth. First, it presents us with a fascinating theory about the origin of the panpipe, an instrument to which I’ve attached considerable importance (see, especially, Chapter Nine), and, by extension, the origins of music itself, one of the principle themes of this book. And not only the origins of music in general, but the origin of the musical notes, and the system by which they are tuned.
Significantly, it associates pipes and/or panpipes with birds (see Chapter Twelve). This is something one finds very often in the literature on panpipes, from many different regions all over the world. And indeed some of the oldest pipes described in the archaeological literature were made from bird bones.
Especially significant are the references to pipes as either male or female. Indeed the story of the Yellow Bell appears to be the source of the fundamental Chinese concept of Yin and Yang. In a great many pipe, flute and panpipe traditions, almost everywhere these instruments are found, from Africa to China, southeast Asia, Melanesia and even the Americas, the division into male and female is important.
And since the story of the Yellow Bell centers on ratios, then perhaps we can think of it also as the story of the origin of mathematics. In fact there are some remarkable similarities between the theory behind the Chinese tuning system and the Pythagorean system of the ancient Greeks. But aren’t all panpipes based on mathematical ratios? In the words of sociologist Marcell Mauss, “a theory of music exists everywhere there are panpipes” (as quoted in Hugo Zemp, "Aspects of 'Are'are Musical Theory" (Ethnomusicology vol. 23, no. 1, 1979)).
Another thing I've noticed in the Chinese accounts is that they are not only about origins but also traditions, and the way traditions are maintained. The Yellow Bell becomes the standard for a great many things that were vital to traditional Chinese society. It began, however, as a wooden pipe and, as such, would tend to expand or contract over time. It was necessary, therefore, for the original process of its creation to be repeated at various times – traditionally at the accession of a new emperor.
One could see this custom as an insight into the nature of tradition, too often misunderstood as the rather boring insistence on continually doing things the same old way. However, as the myth of the Yellow Bell suggests, in order for traditions to continue functioning as such, they must not only be maintained, but renewed (see Sidebar One).
And speaking of origins, my favorite part of this story has to do with the possibility that the whole thing could have begun with a complete misunderstanding. I could be way off base here, and if I'm wrong I hope someone with a knowledge of ancient Chinese will step in to correct me. But if our hero Ling Lun actually was tone deaf, and as a result, actually did misunderstand an order to produce a system of "laws" as an order to produce an arrangement of "pipes," then this too could give us an insight into the meaning of many other venerable and venerated, but also rather strange and inexplicable traditions, which might well have originated in misunderstandings, deceptions, accidents, or other events of a more or less trivial nature.

A Myth is a Lie . . .
I will now proceed to weave a myth of my own, compounded from the Yellow Bell myth interwoven with some of the various yarns I’ve been spinning throughout the course of this book. Before I continue, however, I want to quote one of my all time favorite sayings, attributed to one of my all time favorite artists, Pablo Picasso: “Art is a lie that makes you see the truth.” That for me is a truly profound observation, with enormous resonance in all possible directions. I think the same can be said for myth -- so I'll say it: A myth is a lie that makes you see the truth.
In that spirit, I'll ask some questions that I, for one, find especially intriguing about this particular myth: who was the Yellow Emperor? where did he live? when did he live? what was the Yellow Bell? where was it first created? when was it first created? The assumption behind literally all interpretations of this story is that it takes place at some indefinitely defined "olden time," possibly 2 or 3 hundred, or two or three thousand, years BC, somewhere in China.
To better evaluate that assumption, let's examine a more recent myth about the origin of panpipes, from the United States:

To better evaluate that assumption, let's examine a more recent myth about the origin of panpipes, from the United States:
A story handed down by ex-slaves claims that one evening a slave was feeling low in spirit and heard a plaintive cry of a night bird. The sound inspired the slave to get a piece of cane from a canebrake and cut some holes in it. He then commenced to play a “blues” on his whistle. As time went by, the instrument evolved into a set of “quills.” (The Birds and the Blues, by Max Haymes.)
According to this myth, the panpipe, or as it was sometimes called by African-American bluesmen, the "quills," originated in the United States. We know that can't be true, however, because of overwhelming evidence that this instrument antedates the founding of the United States and, indeed, the discovery of the Americas. So the person inspired by the bird could not have been an African-American slave, as the story implies, but someone who lived at a time far more remote than either slavery or America itself.
I believe the same critical thought process must be applied to the myth of the Yellow Emperor and the Yellow Bell. If we are to seek the truth pointed to by the myth, we must both take it seriously and treat it skeptically, tease out the "lie" behind it so we can see the truth toward which it is pointing.
All the evidence tells us the Yellow Emperor could not have been Chinese and the Yellow Bell could not have originated in China.

True Lies
According to musicologist Fritz Kuttner, the original set of wooden pipes could not have consisted of more than five. The complete set of 12 tones mentioned in the version I cited above seem to have been a much later development. Based on his systematic analysis of the terminology associated with each of the 12 tones, Kuttner concludes that the original set of five pipes could only have been produced prior to the era when tuned bells were being cast. And "Since tuned bells dating from the early Shang II period have been found in quantity, the first partial Lü system [i.e., the original five tone scale] might easily go back to Shang I times."
So far this sounds like pretty ordinary, academic stuff, but Kuttner finds his conclusion "almost shocking, because it pushes the beginnings of the traditional Chinese tone system back into pre-historic times in the direction of the legendary dynastic dates which every serious student of China's history would dismiss as naive. It seems that here we have a musicological tiger by the tail because our conclusion must be unacceptable to orthodox sinology.” (“A Musicological Interpretation of the Twelve Lüs in China's Traditional Tone System,” in Ethnomusicology, Vol. 9, No. 1. (Jan., 1965), pp. 22-38.)
Since I'll be weaving a myth of my own, it won't be necessary to examine Kuttner's reasoning too carefully. Even if it contains a flaw, it nevertheless expresses, as I see it, the simple truth hidden behind an elaborate facade. Because pipes and panpipes are found in many different parts of the world, often among indigenous peoples living in remote areas far from any possible Chinese influence.
In fact, as we learned in Chapter Seven, the distribution of these instruments can best be explained on the basis of a common cultural ancestry, dating from a period well before the origin of any of the Chinese dynasties; dating, in all likelihood to the “Out of Africa” migration itself, anywhere from 60,000 to 90,000 years ago. Assuming this musical tradition did in fact have a beginning, which would be pretty difficult to deny, it was certainly not in China.
According to my myth, the “Yellow Emporer” would have been African, possibly an early ancestor of the Bushmen, who are often described as having yellowish complexions (to go with the epicanthic folds in their eyelids). In certain documents he's described as the ancestor of all the Chinese people, but since in my version he's African, maybe he was everyone's ancestor, the first culturally "modern" human. His assistant, the creator of the Yellow Bell, must also have been African -- though he might not have even been a single person, but possibly a group, all working and thinking together. He might not even have been a he, but a she.
Sinologists will no doubt protest, as Kuttner anticipated they would. But on what grounds? If the Yellow Emperor and the Yellow Bell both date back to some mythical, undocumented, past, then who's to say where -- or when -- they originated? And if anyone wants to claim the originator of the myth clearly intended it to be about China and nowhere else, then we're back where we started, with more speculation about origins -- this time the origin of the myth itself. And who's to say where that got started -- and by whom? As I see it, therefore, my version is at least as good as anyone else's. Better in fact, because, as should be clear from everything you’ve read up to now, it is backed up by evidence.
Sets of pipes are, indeed, an important part of the history of Chinese music, Chinese music theory and even Chinese philosophy. They go back a long way into Chinese pre-history, to at least 1100 BC, the estimated date of a set of bird bone instruments found in a tomb in Henan Province. But as the genetic evidence so strongly suggests, the Chinese themselves did not originate in China, but, ultimately, along with everyone else: Africa.
And, as we work our way backward in time from the earliest migration to East Asia by "modern" humans, I see no reason to assume such pipes could have been “independently invented” in that region, especially since they are now so common, not only in Africa, but so many other places along the original migration path, complete with bird associations, male-female pairing, hocketed ensemble performance, and in so many (though not all) cases, pentatonic tunings. Thus, according to my myth, the Yellow Bell was an African instrument, and the first tuned pipes an African invention.
But why, you ask, is this matter so important? Because, as I see it, the myth of the Yellow Bell is not only about the creation of a set of tuned pipes, but the first tonal system, thus the origin of music itself – and not only music, but also language; and not only language, but . . .
The Centrality of Pitch
In almost all speculations regarding early music and its origins, the most essential element, the use of discrete pitches, and their organization into a coherent tonal system, is either ignored or taken for granted – i.e., assumed a priori with no need to explain how it evolved. Yet if there is any one element of music that clearly distinguishes it from any other type of activity, by any other creature, it is pitch.
In the previous chapter, I discussed the manner in which certain apes and gibbons perform coordinated “duets” and/or “choruses,” which, as I speculated, could represent a “missing link” between the hooted vocalizations of primates, which do not employ discrete pitches, and the yodeled vocalizations so commonly found among Pygmies and Bushmen, which do. While duetting and chorusing are, indeed, very close to “Shouted Hocket,” as widely performed among many indigenous peoples worldwide, neither hooting nor shouting, no matter how highly coordinated, can, strictly speaking, be regarded as music. To clarify, let’s compare an example of shouted hocket with a similarly interactive performance characterized by yodeling. (See Chapter Sixteen for references.)
Shouted hocket: an “esime,” or “interlude” between songs, as performed by a group of Aka Pygmies: Audio Example 56: Aka esime
Yodeled hocket: performed by a group of Huli tribesmen, from highland New Guinea: Audio Example 54: Huli Yodeling
In the first example, I hear only unpitched shouting, while in the second I hear two distinct pitches: A# and F#. And the question is: how did we bridge the gap between the first type of vocalization and the second? And why should the difference matter? Before we can meaningfully speculate on such matters, we need to ask ourselves a more basic question: what is a musical tone?
Phonemes and Tonemes
What might seem on the surface to be a simple step, from ordinary vocalizing (as in hoots or shouts) to the singing (or playing) of discrete pitches, is in fact an enormous leap, with profound consequences for human culture and history. What we have been conditioned to hear when we sing, or play an instrument, is very different from the purely acoustical phenomena produced, as displayed on an oscilloscope or sonogram.
For one thing, the “tones” of music are not individual tones at all, but complexes of sound, with many elements, beginning with a set of overtones, combined with certain resonances, instabilities, possibly some degree of nasality, harshness, breathiness, raspiness, etc. What we think we perceive, is, in other words, very much a social construct rather than a given. This is a situation closely analogous with what happens when we hear a spoken syllable, which, for linguists, can be understood either phonetically or phonemically.

This is a situation closely analogous with what happens when we hear a spoken syllable, which, for linguists, can be understood either phonetically or phonemically.
The phonetic is what we actually hear acoustically, much of which usually escapes our conscious awareness. The phonemic refers to what we hear psychologically, based on certain fundamental sets of culturally determined oppositions, or "articulations," put into play by each individual language.
More generally, anthropologists often use the term emic (derived from “phonemic”) with reference to the culturally determined aspect of any behavior or belief, and etic (derived from “phonetic”) with reference to descriptions of a more objective nature.
There is no generally accepted equivalent terminology for music but there ought to be, because there is a strong analogy at work between what happens when we perceive musical notes as "tonemes" (to use the relatively obscure, but apt, expression coined by musicologist Charles Seeger) and when we perceive spoken vocables as "phonemes." This is not a coincidence, but an important clue to the nature of both music and language -- and the relation of one to the other.
Ferdinand de Saussure, the father of “structural linguistics” and semiology, argued convincingly that language must be understood as “a system of interdependent terms in which the value of each term results solely from the simultaneous presence of the others” (de Saussure 1922:159). The deep relevance of this statement to the realm of music as well has often been overlooked. The key term is “value”—as in the tonal and rhythmic “values” of Western notation. The values of which de Saussure writes can thus be applied not only to the structure of phonemes (understood as classes of vocables) but to musical notes as well, understood “tonemically” as pitch classes, both of which are produced from field-like systems of class “identity” built on culturally sanctioned (“emic”) distinctions.
“In Olden Times”
How does this relate to the Yellow Bell? Let’s recall the myth: “In olden times,” Ling Lun “selected bamboo grown in the Chieh Ch'i valley. He chose only a piece which was hollow and of even thickness.” But that was only the first step. He then proceeded to construct a set of pipes by adding or subtracting a third of the original’s length, thus producing a system through which the pitches of all tones are related to one another according to simple ratios defined by the smallest whole numbers, specifically the powers of 2 and 3.
In other words, he starts with a pipe that produces a discretely defined pitch, but that is not enough. In order for the pitch to be heard meaningfully, it must be part of “a system of interdependent terms in which the value of each term results solely from the simultaneous presence of the others” (see above). In other words, in order to be heard culturally, as a musical “phoneme,” rather than simply acoustically, as either “pure sound” or “noise,” it is necessary for an individual pitch to be part of a rational tonal system. Thus, a culturally determined system of tuned pipes is already the basis for what can only be called a “language,” musical or otherwise, precisely in the sense defined by Saussure.
There’s more: once you have a situation where different “tonemes” are produced by different pipes in a rationally related set, then, as with the phonemes of spoken language, each pipe has the potential to become a signifier – if for nothing else then, at the very least, the tone it will produce when played. Thus, to “notate” a melody you could line the pipes up in order of size and then point to one pipe at a time, in the same sequence as the notes of the melody you have in mind.1 It is then only one small step to the understanding of each tone as a signifier for anything one might want to point to while playing or singing. Which puts us well on the road to a language or, if you prefer, proto-language, consisting exclusively of tonal relationships -- consistent, perhaps, with what Steven Brown has called “musilanguage” (The Musilanguage Model of Musical Evolution, in Wallin, Merker & Brown, eds., The Origins of Music. Cambridge, MA: MIT Press, 2000, pp. 271-300), in which
the many structural features shared between music and language are the result of their emergence from a joint evolutionary precursor rather than from fortuitous parallelism or from one function begetting the other. (p. 271)
Bridging the Gaps
We are now better prepared to return to the question posed above: how did we bridge the gap between simple primate vocalizations and the singing (or playing) of systematically organized musical pitches? To which we will now want to add a second question: given a system of meaningfully organized pitches, or what we might want to call, in Brown’s terms, a “musilanguage,” how did we arrive at both music and language as we now know them?
There is probably no way to answer such questions definitively, as there is far too much information we don’t have, and will in all likelihood, never have. But I do think we are now, after so many preliminaries, in a good position to speculate intelligently on such matters, and in that spirit I will offer the following sequence as a hypothesis worth considering:
1. Interactive "hooted" vocalizations of early primates and pre-humans, along the lines of the "duetting" and "chorusing" of certain contemporary ape and gibbon populations. The adaptational advantage of such behavior was most likely the facilitation of both long distance communication and close cooperation.
2. The morphing of pre-human "hooting" into more or less discretely pitched yodeling could have been an adaptation associated with the transition from a largely vegetarian to a largely carnivorous diet. Since many birds sing using roughly discrete pitches, there would have been an advantage for human hunters in learning how to imitate bird songs as a lure, and yodeling, closely related to hooting, may have been the simplest means of doing that.
3. At some point someone would have discovered that one could do an excellent bird call imitation by blowing into a hollow pipe. Since some of the oldest pipes found in archaeological digs are made from bird bones, this might also have involved a form of imitative magic.
4. There is no way of knowing which of the two previous steps would have come first. Perhaps yodeling and piping developed in tandem, as suggested by the following examples of vocal-instrumental hocket (as first presented in Chapter Nine): Audio Example 19: Voice with Hindewhu, BaBenzele Pygmies; Audio Example 20: Hocket with Voice and Pipe, Huli people, highland New Guinea.
5. More or less isolated pitches produced by either yodels or pipes may have made useful lures, but would still have been a far cry from what we now consider music. They would, no doubt, have been heard simply in terms of how far or close they came to the call of a particular bird. Thus, in order for music to come into existence, there must, at a certain very specific point in human history, have come an extraordinary moment of discovery, every bit as important, in my view, as the invention of the wheel. This is the moment described in the myth of the Yellow Bell, the moment when someone selects a length of cane to make a pipe in the usual way, but then gets the idea of creating a set of pipes, organized according to a system.
It’s important to understand that only through the creation of a set of systematically organized, tangible artifacts could truly musical “tonemes,” as opposed to animal imitations or simple utterances, have come into existence. Regardless of its purely acoustic status, a single tone can never be a toneme. Nor would a set of vocalized pitches have had, at such an early stage, the stability to establish a system of interrelated values, as understood by de Saussure, over time. And since, as we know, almost every human society in the world sings and plays using tonal systems based on ratios very close to the integer ratios associated with the Yellow Bell story, the founding set of pipes would have to have been organized according to more or less the same simple ratios.
6. On the basis of the above sequence, it's not difficult to see how the development of a system of rationally related pitch “classes” or “tonemes” could have led to the development of a language of sorts, based exclusively on tonal relations. Once such a system of tuned pipes is established, we already have, as I argued above, both a “phonemic” and a “semantic” system as well. Each individual tone will now be heard "tonemically," in terms of the tonal structure embodied in the entire set, and will at the same time be in a position to function as a signifier of, at the very least, the note it produces. Could this have been how speech emerged, as a language of pure tones?
7. If the earliest "language" consisted essentially of discrete pitches, then we can see how, for early humans, the development of musical awareness, as part and parcel of linguistic awareness, would have had a powerful adaptational advantage (now lost, of course, since music no longer has the same function).
8. At a certain point this proto-language or “musilanguage” would have diverged into two independent branches -- one leading directly to purely musical interactions something like these: Audio Example 13:Mbuti Pipers (African Pygmies); Audio Example 21: Ede Panpipes (Vietnamese “Montagnards”) (see Chapter Nine for references); Audio Example 84: Chek I Vendelar (the Ouldeme of Cameroon, in Flutes of the Mandara Mountains); Audio Example 85: Kiloloky (the Mikea of Madagascar, from Pays Mikea, Ocora Records); Audio Example 63: Panpipes of Buma (the Buma people, of the Solomon Islands, from Spirit of Melanesia) -- the other leading directly to the development of tone language, as the use of tonal phonemes would have persisted even after non-tonal elements were added. As Steven Brown reminds us, the close association between the two realms can still be heard in the drum and whistle languages of today.2
In sum, the events alluded to in the Yellow Bell myth go well beyond the spatial and temporal borders of ancient China to a foundational moment in “deep history,” a crucial first step in a refining process destined to take us from the raw acoustics of the etic to the first stages of an emic awareness that would ultimately give rise not only to music and language, but so many other aspects of culture, from religion, social organization, kinship, mathematics, astronomy, philosophy etc. to the science and technology of our modern world.
1. One could object that true music notation is permanent, whereas the process I just described is ephemeral and requires memorization. That would be true for the notation of a melody, yes. But each set of pipes can also be regarded as the notation of both a scale and a tuning system. And as such it would have some permanence, at least as much as an inscription on parchment or paper. Moreover, if the original pipes are then used as templates for the production of new pipes, we have a very durable system indeed. As with the digital encoding systems of today, what is “handed down” is not only an original “artifact,” but the process through which the artifact can be continually reconstructed -- and the tradition embodied by it renewed.
2. There is, of course, a great deal more to be said about such possibilities. While I’m not at all sure Dr. Brown would agree with everything (or anything) I’ve written here, I would recommend his essay as a thorough treatment of some of the more subtle and complex aspects of the “musilanguage” hypothesis.
