Ancient Natural Harmony, Maqams and Just Intonation

The art of playing in just intonation can be gradually perfected.

Just intonation refers to the perfectly harmonious intervals contained in certain ancient indigenous musical scales.


Her Magical Eyelashes

This microtonal song in Arabic may have been composed  a thousand years ago… Probably in Andalusian Spain…  It has been preserved in Syria and Lebanon. Ghada Shbeir, a Lebanese singer, has produced a recent recording of this song… We learned it from her recording… and re-arranged it to our taste… A woman is longing for her lover… Her eyelashes are partially closed… seductive…

The song is in maqam saba with some changes into maqam hijaz… The intervals between notes are played in just intonation – perfect harmony…

The rhythm is called ‘awfar masri’… Each measure lasts 19 beats… This extreme exotic rhythm structure is a hallmark of the ancient Arabic genre known as ‘muwashah.’

It is a very smoky, beautiful and unusual song… Kristina Sophia is the singer… Gilly Gonzalez is on percussion… Cameron Powers is playing oud, cumbus and nay… Listen… Relax… Enjoy…

This version of the song may be purchased on CD Baby…

This Review from Mariana
about Voice and Piano
in Just Intonation just came in
and I have to share it!

“The singing with the piano tuned in Just Intonation is amazing! The voice fits into the resonance of the piano when it is in Just Intonation as if the overtones are sound structures and there is room for the voice. I feel and see the overtones play with each other but not fight for space.
As a recording engineer I would have had to lower the volume of the piano (a typically tuned piano in equal temperament) in order to make space for the voice. This is very common in mixing music.. You lower the volume to make space for instruments of similar frequencies. However when the piano is tuned in Just Intonation there seems to be no competition for space between the piano resonance and the voice even when they are in the same range… They do not compete. The sonic structure of the Justly tuned piano has space for the voice.
As a singer this is incredibly fun! And I no longer have to push the voice or make it a more pointed sound to get over the piano… Now there is space and this allows me to use any vocal tone I want or need for the phrases or lyrics… Even softly sung vocals are easily heard within the piano resonance. I wish I could draw it… maybe an oscilloscope would show what is going on with the overtones.”

These perfectly harmonious intervals correspond to the laws of acoustic physics and there is nothing mysterious about them.

Justly intonated harmonies are part of deep ancient musical traditions which enable ecstatic trance.

Traditional Egyptian music scales, called maqams, are a portal into this ancient musical wisdom.

Unfortunately, the modern Western tuning system, known as “equal temperament,” although efficient for transpositions into multiple keys, does not follow these laws of perfect acoustic harmony. Consequently, one of the three most important ancient portals into musical ecstasy remains closed in our modern times. But with deep knowledge of justly intonated microtonal musical intervals, certain possibilities exist.

In ancient times musicians could develop skills in producing perfectly harmonious music. Modern physicists call the intervals between these perfectly tuned notes “just intonation” because the wavelengths of acoustic sound they produce fit together absolutely perfectly.

With the 17th century European invention of the complex machine called the “piano” the system of “equal temperment” was invented so that musicians could transpose melodies into all 12 notes in the octave. Unfortunately, in order to accomplish this, the scales of all 12 keys had to be compromised so that they all are slightly out-of-tune. The result: our modern musical sound fields are flooded with “equally tempered” intervals and we no longer grow up in musically harmonious environments. We don’t even know what we are missing. These are the out-of-tune equally-tempered intervals we listen to today.

This is what out-of-tune equally-tempered interval waveforms look like: 

This is what perfectly-tuned interval waveforms look like: 

Dr. Robert Smith described the newly invented “equal temperment” in 1759 as: “that inharmonious system of 12 hemitones, which produces a harmony extemely coarse and disagreeable.”

And here are the words of Hermann Helmholz from 1852: “When I go from my justly-intoned harmonium to a grand pianoforte, every note of the latter sounds false and disturbing…. On the organ, it is considered inevitable that, when the mixture stops are played in full chords, a hellish row must ensue, and organists have submitted to their fate. Now this is mainly due to equal temperament, because every chord furnishes at once both equally ­tempered and justly-intoned fifths and thirds, and the result is a restless blurred confusion of sounds.”

Fortunately, the musicians in Egypt, Syria, and other parts of the indigenous Middle East, have preserved ancient systems of musical scales known as “maqamat” which have resisted the movements in Europe and America toward “equal tempered” music.

Cameron Powers has spent the last 35 years discovering and learning and mastering musical performance which traditionally employs these ancient “quartertone” intervals, sometimes learning musical pieces which may be as much as a thousand years old.

And yes, these ancient musical scales have flexibilities which allow the performance of “justly intonated” or perfectly-tuned music. It could also be said that musicians using these ancient scales also have the ability to use intervals which are not “justly intonated” and which produce dissonant vibrations similar to those found in modern “equally tempered” Western music. But there is a critical difference: the musician can be in control. He can perform perfectly harmonious intervals to create an ultimately soothing sound environment. Or he can deliberately introduce dissonance to put an edge or create “blues notes” for certain emotional moments induced by the use of these ancient modes.

Cameron Powers has written a “how-to book” for musicians called “Arabic Musical Scales: Basic Maqam Teachings with 2 CD’s” which teaches a total of 45 different ancient scales. Having made numerous trips to study and perform in Egypt, Syria, Jordan, Iraq and Lebanon, Cameron suggests: “The emotional repertoire in these ancient lands is more complex than what we now live with here in America. The pressures exerted by our mono-lingual, competitively-driven, musically out-of-tune dualistic culture which sees everything in black and white simplistic terms has robbed us of the ancient complexity of human feelings. My Egyptian friends enjoy a richer fabric of emotional realities and they have the music to go along with all of it.”

Truly harmonious music, seldom heard in the Western world today, does not even require the musician to invest his own personal emotional enthusiasm. The music alone creates a magnetic attraction and a healing energy field. The possibility for “egoless” music then arises.

“Just-intonation chords are much calmer, more passive; you literally have to slow down to listen to them. (As Terry Riley says, Western music is fast because it’s not in tune.) I’ve learned to hear equal temperament music as a kind of aural caffeine, overly busy and nervous-making. If you’re used to getting that kind of buzz from music, you feel the lack of it as a deprivation when it’s not there. But do we need it? Most cultures use music for meditation, and ours may be the only culture that doesn’t. With our tuning, we can’t.

My teacher, Ben Johnston, was convinced that our tuning is responsible for much of our cultural psychology, the fact that we are so geared toward progress and action and violence and so little attuned to introspection, contentment, and acquiesence. Equal temperament could be described as the musical equivalent to eating a lot of red meat and processed sugars and watching violent action films. The music doesn’t turn your attention inward, it makes you want to go out and work off your nervous energy on something.

On a more subtle level, after I’ve been immersed in just intonation for a couple of weeks, equal temperament music begins to sound insipid, bland, colorless. There are only eleven types of intervals available instead of the potential several dozen that exist in even the simplest just system, and you don’t get gradations of different sizes of major third or major sixths the way you do in just tuning. On a piano in just intonation, moving from one tonic to another changes the whole interval makeup of the key, and you get a really specific, visceral feel for where you are on the pitch map. That feeling disappears in bland, all-keys-the-same equal temperament. As a composer, I enjoy having the option, if I’m going to use a minor third interval, of being able to choose among the 7/6, 6/5, 19/16, and 11/9 varieties, each with its own individual feeling.

Far beyond the mere theoretical purity, playing in just intonation for long periods sensitizes me to a myriad colors, and coming back to the equal tempered world is like seeing everything click back into black and white. It’s a disappointing readjustment. Come to think of it, maybe you shouldn’t try just intonation – you’ll become unfit to live in the West, and have to move to India or Bali.” (Or Egypt or Syria or Iraq…)

“Before the 20th century, European music had its own wonderful non-equal-tempered tunings, which unfortunately we’ve abandoned.”

More Info from
Equal temperament was not adopted because it sounded better (it didn’t then, and it still doesn’t, despite 150 years of cultural conditioning) or because composers and theorists were unaware of Just Intonation. The adoption of twelve-tone equal temperament was strictly a matter of expediency. Equal temperament allowed eighteenth- and nineteenth-century composers to explore increasingly complex harmonies and abstruse modulations, but this benefit was short-lived. By the beginning of this century, all of the meaningful harmonic combinations in the equally-tempered scale had been thoroughly explored and exploited, and many composers believed that consonance, tonality, and even pitch had been exhausted as organizing principles. What was really exhausted was merely the limited resources of the tempered scale. By substituting 12 equally-spaced tones for a universe of subtle intervallic relationships, the composers and theorists of the 18th and 19th centuries effectively painted western music into a corner from which it has not yet succeeded in extricating itself.


“There are regions in the soul where only music can penetrate… The purpose of music is to connect us to, refine and develop our inner life.” — Zoltán Kodály, Hungarian composer

“The first experience of music is of your mother’s voice-even just the way that mothers speak to children all over the world. In whatever language and whatever culture, mothers speak to children in highly inflected speech. ‘Oooh, little one…’ It’s instinctive. There’s something there. So the pitched speech, which is the beginning of music, modulates the relationship between the infant and the mother-as do the mother’s gestures. There’s this kind of song and dance which is the infant’s first experience of human relationship. And it’s all one thing. Song and dance and love are one thing. Which is why to me it’s such a sorrow that, with the professionalization of music in this culture, so many people think, “I can’t sing.” Mothers are not singing to their babies now because the culture is telling them that they can’t sing. And I have pleaded with some young mothers, please, sing to your babies. And some of them are doing it. But one young mother said, “No. I can’t sing. I’m going to give him CDs of lullabies.” So then music for that child doesn’t mean love. It means something that comes from a machine.” — Gail Needleman

“You’re singing different intervals just to tune the hearing, and the voices lock in on the vibration so that it’s really a true, pure interval. Then the overtones start to ring out in the room and you’ve entered the world of forces. I can tell them until I’m blue in the face that these are properties of matter that we’re talking about when we’re talking about overtones. This is physics. This is how the universe is created. And then they hear it. The idea that their inner experience could actually be obeying the same laws as the planets in their orbits doesn’t make any connection. But when they sing one note and hear the overtones that are there, that they couldn’t hear before-that’s a real experience.
And once in a while, one of the students will say, that was like meditation. So something is being received.” — Gail Needleman

“And the other thing I think is really important is how a sense of trust in one’s own experience is really central for our life as a society. It’s not only that those who rely on verification of truth from others are subject to demagoguery, it’s that you can’t have a participatory culture if it’s composed of people who don’t have any trust in their own experience.” — Gail Needleman

“What a shame that is. I mean I would love to be a fly on Pythagoras’s wall. And of course for Pythagoras it was the discovery of the mathematical and physical principles of physics in music. And there was also the esoteric study in ancient Egypt, and healing. It was all one thing. The modern idea of the self-as a monad, in a way, a self-contained, separate unit is new. My sense is that the relationship between people was different then. I heard about a man talking to a woman from one of the Northwest coast tribes. He asked her to tell him something about herself. She said, ‘My mother was so and so from the so and so clan, and my father was so and so.’
And the guy was like, ‘Okay, that’s nice, but tell me about yourself.’ But she thought she had done that. That was who she was-not a separate entity. So we’ve certainly lost that. And music, the most communal of human activities or arts, becomes those billboards with the person with the iPod dancing to music that no one else can hear.” — Gail Needleman

“If a human being is a nexus of vibrations in a world of vibrations, and ancient teachings and modern science do agree on that, then why wouldn’t vibration affect the whole organism?” — Gail Needleman

“Equal temperament and the piano seem to go together. But our music was not born into the world in the shape of a piano. Nowadays more and more pianists are aware of alternative temperaments, and are asking for them. Modern piano technicians – many of whom have mathematical or engineering backgrounds just like their counterparts in earlier centuries – are trading temperament recipes by email and at meetings; programming them into their computerized tuners; writing about them in their magzines and newsletters; attending classes about historical tunings; listening to recordings of pianos tuned in alternative temperaments; and engaging in lively discussions and experiments. In short, temperament is once again on the move. A growing number of contemporary composers are deliberately incorporating alternative keyboard temperaments into their work.” — Anita T. Sullivan, The Seventh Dragon: The Riddle of Equal Temperament

“We have tolerated complete harmonic impurity in our music for over a century in equal temperament…” — Anita T. Sullivan, The Seventh Dragon: The Riddle of Equal Temperament

“Consider the parts of an equally-tempered scale. Each note, as the scale ascends, vibrates faster than the note below it. How much faster it vibrates is a multiple of the vibrations of the previous note. For our equally tempered scale that amount is the twelfth root of two, and cannot be expressed as a whole number or a simple fraction. Therefore, in a sense, it is inexact, and in the same sense the intervals between notes are doomed to be forever parts, never wholes, never finished, but trailing their remainders on out and out into infinity in one of those awful curves that keeps approaching a line but never reaching it.” — Anita T. Sullivan, The Seventh Dragon: The Riddle of Equal Temperament

“Just intonation, at one end of this new spectrum, contains a maximum of “pure” or rational intervals. Total purity is its standard, and while this is not possible on keyboard instruments, as we have seen, it is possible in singing and on unfretted stringed instruments, and can be squeezed out of many wind and fretted instruments with judicious use of finger and mouth. Therefore it is a system that can be realized in quite a lot of music. Equal temperament, at the other end of the spectrum, has almost none of its intervals “pure” or rational (the octave being the exception.)” — Anita T. Sullivan, The Seventh Dragon: The Riddle of Equal Temperament

“After equal temperament came along…then the notion of what “key” a piece was composed in became essentially meaningless.” — Anita T. Sullivan, The Seventh Dragon: The Riddle of Equal Temperament

“Ironically, by increasing the number of chords we can play…we have decreased the kinds of chords we can play. Is there now only one Great Melody that all composers take snippings from?” — Anita T. Sullivan, The Seventh Dragon: The Riddle of Equal Temperament

“Gradually, in ensembles, it came to be that all the other instruments were expected to accommodate themselves to the way the piano was tuned, rather than a kind of general adjusting done by the many wiles and squiggles that music and musicians allow. The piano is definitely more “fixed” than the harpsichord and clavichord in terms of how hard it is to tune, and this is likely one of the cause behind the gradual dominance of equal temperament and the great reduction of intonational flexibility in our music.” — Anita T. Sullivan, The Seventh Dragon: The Riddle of Equal Temperament

“The piano may have, as it evolved (fairly quickly) into a monster with iron in its heart, inspired a kind of technology-grip among composers and performers.” — Anita T. Sullivan, The Seventh Dragon: The Riddle of Equal Temperament

“If exact consonance was no longer even wished for, then what – exactly – was a piano supposed to do?” — Anita T. Sullivan, The Seventh Dragon: The Riddle of Equal Temperament

“In 1688 the first organ was tuned in accordance with Mersenne’s formula for equal temperament…thus setting the Western stage for nearly three hundred years of music’s ‘golden age,’ the classroom for the compete divorcement of the science of music from music theory, the concert hall for the benevolent fraud of equally-tempered modulation, the radios of x million American homes for a twenty-five-year siege by the industrialized harmony-armies of mediocrity…” — Harry Partch

“The novice piano tuner is told that she must first “set a temperament” before doing anything else. This means she will begin in the center of the keyboard, tuning a single note of her choice (usually the middle C or the A just below it), tuning it purely to match a tuning fork. After that, she must tune a little “wheel” of intervals radiating out from that note – fifths, fourths and major thirds – so that each interval is a tiny bit out-of-tune. How much out-of-tune is the “rule” imposed by equal temperament, the keyboard tuning system that has been used on pianos for about 150 years (the piano is about 300 years old).” — Anita T. Sullivan, The Seventh Dragon: The Riddle of Equal Temperament.

Latest historical research indicates Bach did not compose in equal temperament.

Research by Bradley Lehman, 2004, continuing a doctoral project from 1993-4 in “modified meantone” tuning as applied to Bach’s music. The interpretation is based on analysis of Bach’s extant keyboard music, plus a historical study of tuning methods, plus (in 2004) the suspiciously irregular drawing on Bach’s title page.

These loops have been deciphered to represent Bach’s favorite “well-tempered” tuning which preserved individual characteristics for each key played upon his clavicord. Why, we must ask, would Bach have bothered to compose in all the different keys represented in his collection entitled “Well-Tempered Clavier” if he had been using equal temperament which renders all keys to sound exactly the same?

Bradley Lehman has video performances of Bach pieces performed both in equal temperament and also in the “Bach temperament” represented by Bach’s own drawing above. He comments after creating these performances: “The Bach temperament sounds enough like equal to fool just about anybody, and yet…it brings both more intensity and more relaxation to the music. In any event, it encourages me as a player to bend the music more freely and naturally, investing it with more nuances, in reaction to the sound. It makes me listen more closely to melody and counterpoint, the way the musical lines interact with one another. Tonality “locks in” with a subtly different character and mood for every key (scale). Equal temperament, by contrast, goes on and on with a relatively bland inoffensiveness…being less than inspiring, and encouraging “run-on” uninflected performances. The performer has to work harder to make something special of the music. Why not tune instead with a subtle inequality, and let the intonation itself do part of the interpretive work?” — Bradley Lehman –

Hello Cameron
I enjoyed reading about your work and your clear explanation of the true harmonic intervals in Arabic music. I have an appreciation for this quality of pure harmony, as well through building contemporary wind harps and I have found that listening to them over the years has sort of re-tuned my hearing so that I can appreciate the more eastern musical modes.
Thank you for bringing awareness to this beautiful music .
kind Regards,

Now there is an urban legend developing about tuning A to 432 Hz instead of 440 Hz and about how those Nazis were trying to poison us by doing that…

Ben Martens: so are you saying that this article is not on the right track, and we could have a harmonically perfect scale that starts on 440?

Cameron Powers: Yes… We could be playing music in perfect harmony starting on our scales on any frequencies we choose… harmony is created when two notes have a relationship… so what is most important for satisfying our hunger for beautiful sacred music is that the pitches of different notes be related to each other in simple mathematical ratios so that their sound waves can nestle together… like two lovers whose vibes can intertwine…

Unfortunately, when the equal-tempered music scale was created for music mass-production on the keyboard, these harmonious intervals were discarded… why? because in order to play in perfect harmony the pitches of all the notes in a music scale are dependent on their relationship to the beginning note in the scale: the “tonic” or “key”… so in order to be really in tune, all the pitches of each note in a scale will change depending on what key you are playing in…

Musicians who are just singing or playing a fretless instrument like the cello will automatically feel and make tiny adjustments to be in tune in the key they are playing in… but pianos are very cumbersome… you can’t stop and re-tune a piano every time you choose to play in a different key…

So the piano industry back in the mid-19th century became the Monsanto of the music world and sold hundreds of thousands of pianos to an ignorant public with instructions to just tune all the notes with equally spaced intervals: so-called equal temperament…

Just like the public still buys those hard red balls in the supermarket thinking that they are tomatoes, the public is still churning out out-of-tune music from keyboards and fretted stringed instruments and we have forgotten how to listen for perfect harmony as it is no longer relevant… until we explore ancient wisdom and bring back justly intonated perfect harmony we have walled ourselves off from sacred music…

As for whether an A is tuned at 440 or 432 Hz… it makes no difference if we drag the whole out-of-tune equal tempered system down one third of a half-step… there are 100 cents in an equal tempered half step… moving from 440 to 432 carries all the pitches 32 cents flatter… generally speaking, lower pitches are more soothing and higher pitches are more stimulating… so there is a tiny difference… but if we are looking for a way to re-claim the beauty of ancient sacred music then we must re-tune the intervals between our notes by returning to just intonation…

Whenever two different pitches are played at the same time or close together in sequence their sound waves interact with each other… an interval is created… that is what music is… the subject is harmony… that is what we respond to… It has been known for thousands of years that pleasing intervals like octaves, fifths, fourths, major and minor thirds are fractions of each other… measuring string lengths on an instrument shows this…
As for the frequencies (pitches) of individual notes… those are irrelevant for music… a lot of folks find lower pitches to sound warmer than higher ones… hence the feeling that 432 hz sounds better than 440 hz… it’s about 1/3 of a half-step (semitone) lower…
As for numerological symmetries they exist only in the minds of people who have agreed on some mutual measuring standards…
The hertz is named after the German physicist Heinrich Hertz (1857–1894), who made important scientific contributions to the study of electromagnetism whose wavelengths travel at the speed of light. Later, after the 1970’s, it became common to refer to sound waves with the term Hertz instead of “cycles per second”. Sound waves travel at particular speeds depending on the medium through which they pass: in air on earth at about 700 mph.
There is huge confusion in popular music mythology because people don’t even realize that light waves and sound waves are two entirely different things. Attempts are made to equate the “frequency of the earth ” or the “Schumann resonance,” (which turns out to be the average electromagnetic frequency created by all current lightning storms bouncing off the ionosphere at any one time) with musical sound frequencies. Sound waves and electromagnetic waves exist in completely different realms although they can both be measured in Hz.
One main point is that before the 20th century there were no devices for measuring cycles per second. So all the talk about “old tuning standards” is nonsense. The local orchestra tuned to the sound of the conductor’s favorite bell. Or something equivalent. There were no sound recording or measuring devices available.
And the other main point (and this is the most important) is that measuring frequencies depends entirely on which units of measurement are chosen. Seconds are 1/60th of a minute which is 1/60th of an hour which is 1/24th of a day which is approximately 1/365th of a year. There can be nothing sacred about the choice of a system of measurement. It might have made just as much sense to base our “seconds” on the lunar calendar or something else instead in which case the length of a “second” would have been different. So building a whole sacred system based on an arbitrarily chosen system of measurement loses validity fast. Of course you can find lots of cool mathematical symmetries based on lots of numbers but trying to equate one of those to the pitch of a particular note seems silly when seen from outside the box. So called “sacred frequencies” also vanish in absurdity.
If you really want to discover the power of perfect harmony, research the term “just intonation.” That will lead you into the magic of music as it has been known and practiced for thousands of years. And of course the modern tuning system called “equal temperament,” which was created for keyboards, has just about destroyed our abilitiies to “deep listen” our ways into creating truly magical intervals. But new electronic keyboards which can re-tune all intervals on the fly as different tonics are established in a melody will eventually lead us back into the real magic of music.

Schumann Frequencies:

An audio recording is audio, not electromagnetic (radio). It’s the physical oscillation of air molecules, not the propagation of electromagnetic waves. The two have virtually nothing to do with each other. Audio waves do not affect electromagnetic waves and vice versa. So by no science that’s understood would we expect an audio tone to cause a brain’s electromagnetic activity to change its frequency to match an audio frequency.

The confusion arises because the same unit of measurement, Hz, the number of cycles per second, can be used to measure both audio and electromagnetic frequencies without regard to the little detail that one electromagnetic wave at the Shumann Frequency of 7.83 Hz is 24,000 miles long while a sound wave of the same frequency traveling in the earth’s atmosphere is about 144 feet long. Apples and oranges. They have nothing to do with each other.

The Schumann resonances are the name given to the resonant frequency of the Earth’s atmosphere, between the surface and the densest part of the ionosphere. They’re named for the German physicist Winfried Otto Schumann (1888-1974) who worked briefly in the United States after WWII, and predicted that the Earth’s atmosphere would resonate certain electromagnetic frequencies. 

Lightning is constantly flashing all around the world, many times per second; and each bolt is a radio source. This means our atmosphere is continuously resonating with a radio frequency of 7.83 Hz, along with progressively weaker harmonics at 14.3, 20.8, 27.3 and 33.8 Hz. These are the Schumann resonances. It’s nothing to do with the Earth itself, or with life, or with any spiritual phenomenon; it’s merely an artifact of the physical dimensions of the space between the surface of the Earth and the ionosphere. Every planet and moon that has an ionosphere has its own set of Schumann resonances defined by the planet’s size.

The amount of resonance fluctuates as the ionosphere becomes more or less dense, which depends largely on the amount of solar radiation striking it. At night, that part of the ionosphere that’s in the Earth’s shadow thins out. Another influence is that the world’s three lightning hotspots — Asia, Africa, and South America — also follow a day/night cycle, and are seasonal as well. Thus, the peaks of radio signal strength at the Schumann resonance follow a constantly shifting, but reasonably predictable, schedule.

A very important point to be aware of is that this resonated radio from lightning is a vanishingly small component of the electromagnetic spectrum to which we’re all naturally exposed. The overwhelming source is the sun, blasting the Earth with infrared, visible light, and ultraviolet radiation. All natural sources from outer space, and even radioactive decay of naturally occuring elements on Earth, produce wide-spectrum radio noise. Those resonating in the Schumann cavity are only a tiny, tiny part of the spectrum.

Nevertheless, because the Schumann resonance frequencies are defined by the dimensions of the Earth, many New Age proponents and alternative medicine advocates have come to regard 7.83 Hz as some sort of Mother Earth frequency, asserting the belief that it’s related to life on Earth, despite its being so tiny and lost among all the other, stronger parts of the electromagnetic spectrum. Often we find that New Age beliefs are often based more on what seems emotionally satisfying than on sound science.

The most pervasive of all the popular fictions surrounding the Schumann resonance is that it is correlated with the health of the human body. There are a huge number of products and services sold to enhance health or mood, citing the Schumann resonance as the foundational science.

Hi Cameron
How are you?
My name is mario and i write you from Spain.
Thanks for your great contribution so that lovers of Arabic music learn with your books and cds.
I have bought Arabic Musical Scales and a few weeks ago Harmonic secrets of Arabic Music Scales.
I am a follower of the Just Intonation and I must admit that I’m confused with your interpretation of the jins of the Arabic maqamat.
I would love please you clarify my doubts.
The Rast tetrachord always has been T_M_M
Tone_Median and Median
I have read Al Farabi interpretation was:
C 1/1 D 9/8 Eb- 27/22 F 4/3
and your interpretation of Rast is:
C 1/1 D 9/8 Eb- 5/4 F 4/3 (turkish rast)
9/8_10/9_16/15 . (this is really T-T-S not T-M-M
you have interpreted the Rast the same Ajam in your book
Is a mistake of your book or you really think so?
Also Sikah jin is M-T and in your book is S-T (16/15-9/8)
Rahat el Arwah is Huzam beginning in Bb-
In your Huzam is:
In your Rahat el Arwah is:
Why you change the relative ratio of the two maqamat if must be the same?
Thanks in advance

Hi Mario!
Sorry for slow response… I’m slow these days because of surgical work on my spine… I seem to be getting old…
But I am very interested in your comments…
I am reviewing my own analysis in my Harmonic Secrets of Arabic Music Book
Rast: pages 71-3
Huzam: pages 86-7
Rahat el Arwah: pages 94-5

First I have a question for you: did Al Farabi specify these justly intonated fractions or did he just make fretboard diagrams and later writers specified the fractions?
Although tradition counts for a lot in Arabic music I’m not sure how much influence Al Farabi’s personal preferences still have on players today… My assumption is that with deep listening skills we all move toward just intervals… but there are a lot of just intervals to choose from… My experience is that the 3rd note in Rast (the E half-flat) in Egypt tends to be the 11/9 which is very close to the ET quartertone while in Syria the prefered E half-flat is the sharper 16/13 while in modern Iraq and Turkey they have pushed the E half-flat all the way up to the 5/4 which does make it identical with Ajem…
The 27/22 interval is just a bit flatter than the 16/13 interval…
So if you are playing an ancient instrument like the oud your ear might be drawn at different times to different just intervals when they are so close together…
As for Sikah and Huzam and Rahat el Arwah… they are such gardens of multiple possibilities that it would be foolish to try and nail down one definition and call it the most used… I suggest some of the different ways to enter these maqamat particularly on pages 94-95…
I am such a fan of Rahat el Arwah that I tune my bottom oud string to B half-flat… So with than note glorified by an actual open string I am setting up certain interval preferences by choosing the pitch for that oud string…
Of course if you are tuning a keyboard then you will be drawn to try and define these intervals exactly…
I have a Yamaha keyboard hooked up to a TBX1 pitch control box and I have defined three versions of Rast in that box… one for Egypt, one for Syria, one for Turkey and Iraq…
So the differences in my book regarding Sikah vs Huzam vs Rahat el Arwah jins are meant to reflect the multiple possibilities… There is no way to define these exactly either historically nor in present musicianship… that is my opinion…
Just listen deeply and make each song sound really good… that’s the opportunity we have with just intonation…
Thanks, Cameron
