مصر أم الدنيا

first published locally 26/9/07
The title of this post is a proverb or expression that appears to have been in colloquial usage and in popoular media for at least the latter half of the twentieth century. it means egypt is mother of the world. In the 1990s, reading some speculations by genetic scientists has provided added meaning to that phrase.

Some sort of genetic information analysis which I should hopefully re-look up and cite sometime later indicates that the current "stock" of humans, get this,
a. belongs to the same stock
b. seems to descend from a group of about 500 000 people somewhere in africa
some two or few decades of millenia ago, iirc, about 100 0000 years ago.

I don't recall the rationale behind these conclusions, which by themselves beg substantiation and elaboration.

Current paleontologic thinking also supports the idea that humans originating in africa, fanned out to the rest of the world. So the geneticists' "stock" eventually migrated out of africa onto the fertile crescent then the autral asian coasts , turkey minor, and beyond to asia and europe. Apparently historical evidence shows that the former were the earliest routes taken by the african migrants.

If this were so, then considering the routes out of africa, the northeast coast does seem to be the most likely route. Assuming that sea crossing was for long preceded by sailing along coastlines, then one supposes the way out of africa, either by sea or by land was indeed the egyptian realm, comprising both the coasts of sinai , opposite which the asian coast is visible to the naked eye,
as well as the land route across north sinai .

On the way those migrating africans would have followed not only the eastern african coast, but the much more likely route of the very long river Nile, which finds it sources deep in the center , in kenya.

Those migrating africans would have thus interacted with egyptian society, and some may have settled in it and therefore contributed to it. Perhaps also the sedentary egyptian population contributed also to the outward asia-ward migration.
Being a bottleneck of sort to early or first human migration out of africa, the phrase opening this post takes on a new sheen of credibility or possibility that egypt is indeed (figuratively speaking) a mother of the world.

Some problems arise however.

Was that out-of-africa migration a wave, a series of waves (how long were intervals?) or in continuous fluctuating streams or trickle of human movement?

But why then do traces of the oldest civilisation in egypt date back only about six millenia, and not as far back as true settlement which must have somewhere near or at least halfway to those 100 000 years ago.

The small size of the population at an early age, would not account for a huge migration. Supposing a slowly growing group of 500,000 humans began trans continental movement, it would have or must have amounted to a trickle if stretched across a long period of time.

How does this out-of-africa theory tally with the earliest accounts of population in various regions around the world? What constraints would the earliest available population estimates in addition to proposed population growth rates preceded those estimates, put on the sizes and destination of out-of-africa migrations supposing they began about 100,000 years ago ? Can such consideration hint at other ages for out-of-africa migration?

The out-of-africa theory is not quite aligned with religious cosmogonic accounts (let alone other mythological (or defunct religious) ones). I'm almost certain hindu traditions place humanity's beginnings in the subcontinent or near it.

The abrahamic traditions seem to point a fertile crescent, levantine or rather mesopotamian patrimony to the major peoples of the region, including the "founders" of nations , viz. the hamitic - like egypt, libya and punt - and the semitic nations. On the other hand, the latter or modern abrahamic tradition does not address the origin of all nations (except through adam and some of his progeny) and thus it does not claim an anthropogenesis for all nations, except in the person of adam and thereafter limits its scope to the hamito-semitic nations.

So in this sense at least the abrahamics are not necessarily in direct conflict with the geneticists' out-of-africa thesis, except on matters of evolutionary speciation of humans, aka "homo sapiens sapiens" to the geneticists.

Visiting the animals at the zoo

I could watch dozens of hours of David Attenborough documentaries sampling pictures of hundreds of fascinating nothing short of the psychedelic creatures that populate or once populated our big blue marble. it would be nothing however like walking up to the animals and see them live, up close, being in their presence.

Being close to those sad majestic odes to beauty and perfection, to their innocence, their beauty their very unhuman shapes sizes colors and demeanour is an experience of mystical proportions to those who can appreciate it, even at a sad place like the zoo.

Exchanging looks with a giraffe, or a llama or dromadary; watching ruminates approach the fence in expectation of a snack; watch parakeets talk among themselves, watching a parrot with fanstastic plummage yawn are all the stuff of fantasy and dreams.

At the zoo, especially in my nook of the woods, however there are other distressing scenes. There was a lion crying, (crying if he is anything like my cat when he cries) imprisoned and pacing in his outer cage to entertain by his mere presence people under the blare of loudspeakers pouring the most obnoxious popular music from the vendors kiosks 5 meters from the fence. This was one of my saddest moments at the zoo.

It is unfortunate this contrast between the glorious feelings I get from being in proximity to such life forms and the inevitable sadness that attends one's entry into any zoo. The story of kidnap and captivity and then being kept for life in poor and highly abusive conditions.

It would be nice to take kids up close to the animals , in the safety afforded by the zoo. But what of the moral responsibility and inescapable guilt and sadness?

I would think of it like taking them to a very special shrine, but in a very dilapidated area. I still think the trip to the zoo is worth it.

I find wonder in the height of the giraffe, the intricate musculature of the dromadary, who ironically approaches in resemblance the computer-generated movies of dinosaurs, in the patient resignation of the pelicans in the searching gaze of a llama or a peacock, or the familial atmosphere in a parakeet house.

Wonder like that to be found when one sits under a few trees, and looks up at the canopy of branches and leaves above, long enough to weep at their beauty, their gentle but unremitting complexity, at the subtlety of their creator. ... Read more

Searching non .edu web resources

The following are tips for searching academic web resources (web, ie, available to the www) at academic institutions with tld other than "edu" which is used widely and almost exclusively only in the US , which limits search scope.

Some web engines provide syntax to restrict a web search to a specific class of sites.
For instance, the query "quantum +site:.org" for the google search engine will restrict search results to only sites that have a domain address ending in .org. The + signs means that the site criterion is required. Without it, results matching the site: criterion will be given higher ranking in the results set, but the set may also include non-matching results.

Other search engines have different names for the site criterion.
yahoo
altavista "host:"
webcrawler
google "site:"

Restricting the search to just universities omits a lot of research centers that would have .org domains (TLD's). But it is a good first step in focusing a web search on academic resources.

The most famous academic top-level domain is .edu . Unfortunately most sites with domains ending in .edu are american universities. So a google search query like "your search terms +site:.edu" will limit the result set to only academic resources in the US.

To expand the result set to other parts of the world, we first identify the domain naming patterns corresponding to a given country's universities, then we use that in the site criterion.

For Belgium, Japan and the UK, academic website domains end in an ".ac" followed by the country top-level domain, "*.ac.be", "*.ac.jp" and "*.ac.uk" respectively.

A web search query to cover these three countries would include the criterion, "site:.ac.*"

In Germany, university usually have the domain name prefixed with "uni-*.de". So a query might look like "host:*.uni-*.de".

Other countries, like argentina, use the top-level "*.edu." where country-tld is the country top-level domain. To search results in all countries that use this convention, use "site:.edu.*" .

Generally, if curious about the information from a given country, run a search for its universities and see how the domain is formed, then search for that pattern (the top parts of the domain). ... Read more

can the UML be testable?

Recently i read someone promoting their own software modeling framework on some website. In explaining the advantages of his own system he remarked that UML "failed" because it was not testable or verifiable. The writer , however, is wrong in this assertion. I believe that the UML is testable and verifiable because (and assuming) it is directly mappable to source code, which is at least testable to the extent of the system requirements.

Now the idea of testability and verifiability is very important. and indeed these are two important criteria for well-designed software.

In a more general sense, when speaking of models in science, a crucial step in developing them is testing them, and their verifiability is also crucial in their acceptance and adoption.

So what about The UML? It is such a handy tool of design, it has become sort of the autoCAD or the HDL but for software instead of civil engineering or microprocessor design.

The UML to software is actually much more than what AutoCAD is to civic or mechanical engineering or HDL for chip design.

the UML is directly mappable to software, which can then be tested.

Whether the UML without code generation is itself testable might merit a web search. ... Read more

The wages of neglect

One of the characteristics or recurrent themes of repentance is that when the subject decides to make up for the things they had till then shirked , the means to do so are removed as though held back.

Sometimes a subject (a person with a sense of self) neglects reneges or shirks a certain duty be it an act of piety or one of sacrament or ritual. The subject does so even though the opportunity requisite for carrying the act is present. It may occur that when the subject decides to perform the neglected duty, the opportunity for doing so is removed. Be it mobility, health, money, food, water, the presence or access to a person or an object, whatever the means or opportunity are, they are removed and the sujbect is no longer capable of 'making amends' as they had intended.

To give an (imaginary) example the case of someone who neglects acts of charity while they can afford them and who once they resolve to fork out the requisite charity find they are no longer able to afford it. Or someone who is not good to their parents, but only realizes it or resolves to treat them well , after their death; a resolution that of course comes too late, and becomes more remorse than compensatory / action.

one way to verify whether this indeed is a recurrent theme (or case) would be the presence of popular or canonical proverbs that refer to such a situation. Such proverbs would be loosely along the line of "if you don't use you lose it."

Finally, this pattern is not necessarily true for every subject, but only in certain cases. ... Read more

a reference on musical scales from usenet

the following is excerpted from this post from a very laborious and contentious thread on the rec.music.makers.piano newsgroup. I do not know what his source is, but for my reference:

"Greek music theory derives from Egyptian and Mesopotamian predecessors, which were developed to account for heptatonic music.

We know what the instruments of the time were like. Flutes, auloi and lyres were all designed for 7-note scales. We have a Sumerian description of a tuning algorithm for a heptatonic harp and we know of some subtle refinements of design like auloi that came in two pieces so you could mix and match upper and lower tetrachords from different modes (exactly the way makams are conceptualized in the Middle Eastern music theory of the present day). There is not one surviving physical artifact or description of an instrument that suggests the ancient world used pentatonic scales.

> and the Japanese took a different direction

They didn't. They borrowed the Chinese pentatonic scale from China,
as a late development. "

D'ailleurs la théorie traitant de la construction de gammes diatonique et pentatonique me dépasse. Je n'en sais qu'on y distingue une construction historique, voire une évolution de pratiques, et d'autres basées sur des modèlizations conceptuelles de la génération de notes (tons) de musique, dont le cercle de quintes la série harmonique, et les systèmes de tempérament à intervales mesurées sont les exemples les plus connus auprè les non-spécialistes. ...

etymology note: Sherry

Sherry's spanish name is , el Xérès, sometimes also written el Jeres, after the name of its city of origin, Jerez de la frontera. These three variations on the same name comprise the brandname of the region's product Jeres-Xérès,-Sherry. Its land of origin is a trianglur region in the southernmost province of spain, cadiz, comprised of Jerez, the river guadalquivir (الجدول الكبير) and the city or town of sanlucar in the west, which is a producer of another wine made with the same process but whose brandname is Manzanilla-Sanlucar de Barrameda registered as the former in 1933, and puerto de santamaria in the south. Jerez is also known for its Jerez vinegars, made from the same wines of Jerez.

The region also produces vinegar out of the same wine. Of the three types of soil, the lightest and the best for the palomino grapes used in the production of the fino and orroso wines of Xérès , is called albariza (meaning standing out, en relief). In the step of the vinification process of Sherry wines, known as the solera system, three rows of barrels are arrayed atop each other, each containing the same wine but of a different age ordered youngest to oldest, from the top to the bottom row. Periodically, a third is removed (soutiré) from the bottom barrel, and replaced with a volume from the barrel above it, containing the younger batch. The removal of the liquor from the oak barrels is known as saka, which i only speculate may have derived from the verb saqa , ar. سقا.

The time of its adoption by its biggest fans, the brits, dates sometime between the 16th century and the 19th century.

The amount of stuff that interests the british in Spain, or in the Iberian peninsula in general, is bemusing. Some Brits apparently are also very fond of porto, which is another wine, originating from Portugal this time, whose production there is regulated since at least the seventeenth century.

Finally, and since all those etymology notes are largely conjecture, I'll venture tha t the namesake of the muted wine, el Xérès, may actually also come from the arabic word for beads, Kharaz , خرز . ... Read more

The Magdeburg hemispheres: Guericke thermodynamics and the history of flight

 

One of the episodes in the history of flight involves two aeronef designs that trace their inspiration to an experiment that may or may not have contributed a bit to the development of the ideal gas laws by Boyle and Hooke, which themselves led to the development of the first steam engine. In effect, the little episode , fruitless in the history of the development of flight, shows links with other episodes in the history of science and technology.

The designs in question concern first a 1709 airship proposal by a portuguese scientist named de Gusmao whose designs for aero lift involved the exploitation of lighter than air volumes that would carry the ship up. He was renouned for making a model balloon fly up to the roof. His airship design involved an apparatus or grid to to heat the air underneath a canopy that covered the airship, a conceptual predecessor of the hot air balloons. He was encouraged in his design efforts by another lighter-than-air idea, 37 years older at his time, and unfortunately impractical , by a Fransisco di Terzi, who imagined an airship relying for its buoyance on thin copper vacuum spheres .

Terzi's idea of the vacuum spheres , and the calculation of the relative weights of the air-less copper spheres and their equivalent in air, was in fact, despite the oversight quite brilliant and sensical. Yet it derives from another vacuum sphere , one that was developed twenty years earlier.
That sphere, as it turns out, was a much more famous sphere, that in fact was not a sphere but consisted of two hemispheres named after the town where they were conceived , Magdeburg.

The two hemispheres of copper , about a foot in diameter, were made in 1650 and demonstrated repeatedly at royal courts through the following dozen years by the german scientist and public servant, Otto von Guericke who set out to demonstrate the power of the pressure of gazes like the air and fluids like the atmosphere. In so doing, he wanted to disprove a long held notion , originating with Aristotle, on the reason why solids were held together so tightly , what made substance, utterly divisible into dust particles, be able to hold itself.

Artistotle's proposition stipulated that nature abhors a vacuum, and in the same way , earth is attracted downward and fire is attracted upward, there was a natural disposition to fill in in gaps in space causing matter to condensed in its solid forms. This interpretation of his thus came to be known , by Guericke's time as "horror vacui".

Guericke seemed to believe that it was rather the pressure of the air , a force of our atmosphere that held solids together. An erroneous notion that can be more than forgiven for the ingenuity with which he set out to prove it.

The hemispheres were to be brought and held firmly together after covering their rims with a layer of grease or naphta oil. They were then to be emptied of their air content by means of an air pump von Guericke had developed specifically for the experiment. Once devoid of air, the hemispheres became so tightly held together that no amount of available force could do the work of displacing them apart. To demonstrate this fact each hemisphere was tied to a team of horses , both facing opposite directions. Both teams would then be made to pull the hemispheres in opposite directions, but no matter how hard the horses pulled the hemispheres held tightly. the enormous force of atmosphere pressure on the vacuum inside the sphere held its hemispheres together.

In setting up this experiment Guericke demonstrates some fine details.

- The experiment was a success and was even popular , making it part of popular knowledge not just insular recondite science.

- The experiment's apparatus was the world's first artificially (human) made vacuum enclosure. This particular activity, creating a vacuum , is very important to the advancement of modern chemistry, and later electronics.

- The design of the air pump to create the vacuum went on to contribute to Robert Hooke and Robert Boyle's work and consequently to the prolegomena of modern chemistry and thermodynamics that they both have laid down. Other chemistry researchers followed Boyle and Hooke's example and made use of Guericke's pumps to enable to examine chemical propertie and reactions in a vacuum, greatly aiding the advancement of chemical science. Vacuum flasks and tubes later carried electrical research through the invention of incandescent and fluorescent light , the radiotelegraph and the radio , and the vacuum tubes of the television and the computer.

الخان و الخاقان و القان و القانون

ملاحظة لغوية

كلتا الكلمتان خان و خاقان تعدان مترادفتان بحيث أن معناهما واحد و هو حاكم أو ملك فى حين أن لفظ خاقان فيه تعاظم على لفظ خان حيث يشابه فى معناه اللقب الفارسى شاهنشاه و معناه ملك الملوك ، و يكتب اللفظ فى اللغات الرومانسية هكذا Khâgan

و اللفظ خان أو قان من أصول مغولية أو تركية و الأغلب من أصل مشترك حيث تتشابه اللغتان الى حد بعيد فى أغلب مفرداتهما. و لدى الصينيون تحوير ثالث للقب خان و تعريبه هان، و تكتب كلمة خان هكذا بالصينية

可汗 .


و الخان أو الخاقان إسم مذكر ، مؤنثه ختون و خانوم و ربما يرجع اللقب المؤنث هانم الى مؤنث النطق الصينى للكلمة، هان .
و فى حين أننا نجد أن كلا الإسمان مستعملان فى الخطاب التاريخى العربى ، نود الإشارة الى إستهجاء أسيوى لنفس الللقب ألا و هو القان (هذا الى جانب المرادف الصينى هان).



تجدر الإشارة أيضا فى هذا المضمون أن الأسم الذى إشتهر به موحد أمبراطورية المغول ، جنكيز خان أو جنكيز قان ، هو فى الواقع لقب ترجمته الحرفية هى حاكم المحيط بمعنى حاكم العالم
، فى حين أن إسم هذا القائد الأصلى هو طيموجين.

مع مقارنة المرادفات الثلاث ، خان خاقان و قان ، و التفكر فى معناهم نرى أنه ربما هناك علاقة بين هذا اللقب و معناه المشتمل على الحكم و أصل كلمة القانون.

هنا نرى إمكانية القرابة بين القان الذى يسن القانون. و هى قرابة إن كان حقيقية فهى تشابه القرابة بين بين كلمة السياسة و أصلها اللغوى و هو الياسا و هى التشريعات التى وضعها جنكيز قان عند جمع قبائل المغول تحت رايته و إنتصاره على ممالك الصين الشمالية.


نود أيضا مقارنة التركيب اللفظى فى الألقاب شاهنشاه و قائمقام مع تركيب خاقان ، أما فى اللفظين السابقين فلا يخفى الأثر التركى و إن كانت شاهنشاه فارسية ، أما فى اللفظة الثالثة فربما تدل على أن قان قد يمثل الجمع للمفرد خان.

من الممكن أيضا وجود قرابة لغوية بين لفظ خاقان و كلا من اللقب اليابانى شوغان و اللقب العبرى حاخام ، و إن كان فى الأغلب تشابه عابر . حاخام تتصل بالمصدر حكم و معناها حاكم أو بالأحرى حكيم ممما يدفعنا لمقارنة الأحرف حـ كـ م و الأحرف خ / ق ن
أما الحرفان ح و خ فهما قابلين للتبادل فى علم و تاريخ أنساب الأسماء , نجد كذلك تقارب صوتى بين الحرفين ك و ق الى جانب تقارب مكانى إن صلح التعبير بين الزوج م و ن حيث نجدهم متجاورين فى معظم الأبجديات

كنت أتسائل ما اذا كانت الحروف خ و ه و ح قابلة للتبادل مع حرف أو صوت شين مثلما هو الأمر مع والحروف أو الأصوات اللاتينية c ch kh k
فربما ساعد ذلك على يشير ذلك الى أصل مشترك للقب المغولى خان و قان و مقابله الفارسى شاه ، و لكن هذا غير صحيح لأن تسمية شاه إنما ترجع الى السانسكريتية گذشته.
يجدر التساؤل أيضا عن تاريخ استعمال هذا اللقب فى أراضى السند و فارس.

كذلك أفتقر الى أصول و تاريخ غستعمال هذا اللقب، و إن كا ن هنالك إشارات تعود الى ما قبل عصر جنكيز بزمن. فعلى سبيل المثال نجد أن البلغار النازحين من القوقاز الى أراضى التراقيين فى القرن السابع الميلادى تأسست إمبراطوريتهم اﻷولى حوالى عام 632 م على يد ملكهم المسمى خان أسباروخ ابن المك خان كوبرات .
و الذى انتصر من ضمن آخرين على مملكة اﻷفار فى الغرب و التى كانت أيضا تعرف بالخاقانية.
و قد قدم اﻷفار أو اﻷواريون و البلغار من القوقاز ، و يعتقد أن اﻷفار اﻷوربيون قد يعودوا فى أصولهم للروران ( تان تان أو شيانباى) ذوى الأصل المغولى و الذين إستعملوا لقب الخاقان منذ القرن الثالث الميلادى. هذا الى جانب أن البلاد التى سكنتها الشعوب التركية فى حقبة ما بعد إنهيار إمبراطورية الرومان كانت تعج بالخانات (خانقاه) مثل الخزر و الأفار .

و ﻻ يسعنى اﻻ أن ألمح الى تقارب الخاقان و بالتحديد اللقب اﻷقدم المستعمل لدى المغوليين اﻷول ، كيهان (可寒) مع الألقاب السامية كاهن و حاكم . و من التحوير العبرى لكلمة الحكمة ، خُخمة، نجد المرادف للحاكم أو الحكيم فى العبرية هو حاخام أو خاخام و هنا نجد وضوح قى تشابه اﻷخيرة مع اللقب المغولى ثم التركى ، خاقان.

Isao Tomita is one of the most remarkable Japanese composers and recording artists.

His music has provided me, an amateur musician, with a certain sense of vindication in terms of an approach to
music that tends to transcend traditional forms, in terms of their accoustics, harmonies and thematics.

[ It may seem that the same can be said of so-called "world" music - and as it happens Tomita has featured on recordings that are labeled "world" music or ethnic (as with Nasco Fantasy recording with the Japanese taiko drumming group Kodo) - but we're not talking about world music here ]

But Tomita's work is classical music music that departs from the traditional sounds of accoustic instruments into the vast world of synthetic sounds. Sounds that are engineered with the same ingenuity used in his music composition.

Thematically Tomita is a classical composer, most of the time, but essentially his are modern compositions that can span with ease the spectra of classical, experimental, and electronic music as also ,i daresay, even jazz.

His music has, to me, an inescapable familiarity that is felt with only the best composers like Beethoven, Debussy, McCartney, Wonder, Coltrane or Zappa. But that is also because Tomita's music includes a lot of interpretations of classical works.

Tomita recorded / interpreted / covered Debussy works (whichever your musical persuasion is) in his first album issued in 1974, Snowflakes are dancing, such as Suite Bergamasque no. 3 , better known as Clair de Lune, of which i think there 's a free excerpt at the artist's page for the album.

True to his title as a President of the Japan Synthesizer Programmers Association, the master composer provides a tally of the equipment used on his albums at his web site (at least the dot org site) together with images and samples liner notes and other information.

He has made modern classical compositions, and has been a renouned classical composer and motion picture composer through the 1950s and 1960s. as well as others more akin to the socres of Scott Bradley and Raymond Scott during the 1950s.

This familiarity in the music along with the pensive musical landscapes fashioned by both the composition and the sounds used, gives Tomita's works haunting qualities.

Perhaps those electronically induced soundscapes may not be everyone's liking now or ever, but it is certain that they are timbral territories that have only been explored for the past six decades, less than a hundred years.

In terms of centuries, the mozarts, Bachs, Davis and Coreas of these new soundscapes, may have not yet appeared. but of those, Tomita certainly gives us a more than a few hints.

beschreiben timbre

Often people try to characterize types of timbre quality as fat, deep or in terms of having colour.

but calling the sound of 3 overlapping oscillators "Fatter" just because there are more sound sources is a bit inaccurate. It seems color is naturally suited to describe differences of timbre between instruments.

A friend once observed that "colour" was a pretty natural choice of metaphor when describing the timbre of a sound, refering to the fact that the presence of multiple frequencies is at play both in the visible light waves we call colour and in the waves of musical tones.

In general, the timbre of a given musical sound (indeed any sound) is determined by the harmonic content of the accoustic pressure wave. OK statements like this are deceptively simple (save perhaps for the term harmonic to some readers) but they contain within a great deal of information. Let's simplify this statement and explore the concepts it encapsulates.

For starters, if the term "harmonic" sounds confusing we can do without it for now, because in any sound wave there are two components (among others) that make up / describe the qualities and characteristics of the wave: Amplitude (the loudness of the wave over time), and its frequency (the number of times the periodic waveform is repeated in a given unit of time). The latter , frequency, or rather a multitude of frequencies - combined together (added, interfering) to form the Waveform of the sound , ie the way the wave's amplitude looks during the time of a single cycle of the wave - make up the harmonic content of a wave.

I would also like to add that when I speak of waves I shouldn't only be speaking of accoustic or sound waves, which because they travel through air contracting and expanding it, I like to call by their other physical name, pressure waves.
There are also electric waves. And much of what gets said of the sound produced by material accoustic instruments , also applies to waves of electrical current, voltage waves , or electrical signals, streams of them. These are usually produced not by material accoustic instruments but by electric circuits that generate waves of different types and that modify them in different ways, (this is called synthesizing) and then drive loud speakers which convert the electric current waves into actual sounds that we hear (this is called reproduction). The electric waves themselves could also be analogs of wave information initially produced as binary data that describe all the properties of the waves produced, from waveforms to full performances. This binary data, called digital, is converted to an analog electrical wave or signal or current (stream) , using a device called DAC (Digital to Analog converter), and eventually the "analog" electric current is itself converted into accoustic sound waves or pressure waves, which are audible analogs of the electric current waves, and that travel in the air to reach our ears.

Let's simplify the earlier statement and then proceed to discuss the waves and their timbres.

In general, the timbre of a given sound is determined by the content of its wave.

The wave itself is a composite of several other waves, all added together - That is, they produced pretty much at the same time, and their intensities (loudness) combine to give the total loudness of the wave. These several other waves have different loudness values but are all considerably lower than the loudest composite wave, which has a frequency equal to the pitch of the musical note being sounded.
This loudest wave is called the fundamental, and the other less intens waves are called the overtones of the waves. The fundamental and the remaining overtones are also known as the harmonics of the wave. Each one of the overtones (aka harmonics) has a frequency that is a multiple of the frequency of hte fundamental, that is a multiple of the musical note's own pitch. I won't get into the arithmetic and trigonometrical relations between the harmonics here now because I'd like to focus on timbre now. But I'll say the easiest representation of the relationship (ratios) between the harmonics (and their frequencies) is the famous one using the length of a guitar string.

Because the overtones have frequencies that are multiples of the fundamental harmonic of the musical note (or electric signal), the harmonics of any sounds are distributed over the same values of frequency, namely, (f, 2f, 3f, 4f, 5f, ... and so on ).
What differs from sound to sound (among other things) is the relative loudnesses of the different harmonics.

There are other factors affecting timbre, such as the relative phases of the harmonics of the wave, as well as the presence or absence of other waves combined each with its own set of harmonics. But I believe the relative loudness of the overtones is the crucial factor in a sound's timbre or colour.

The harmonics of an accoustic instrument depend on the materials of which the sound generating components are made as well as the shape of the sound box of the instrument. The shape and materials of a violin's sound board, the hairs of its bow, the make of the strings, affect the harmonics of the instrument, and so despite the kinship different violin instruments sound different from one another. The same is true for most other instruments. Even playing techniques affect the tones' timbre.

Now when we want to look at a representation of the harmonics of a given wave, we have to use a diagram that plots Amplitude against (not time as in the more familiar wave diagram - called time domain diagrams but against) Frequency.
Based on the aforementioned, we should expect to see that at the the frequency of the fundamental the amplitude has the highest value, and that the other overtones appear in the graph as spikes in amplitude right where each overtone's frequency is on the horizontal axis. Here is a sample diagram of the harmonics of a wave produced on a VST synth and plotted by the FREE fre(a)koscope 0.8 spectrum analyzer plugin,



The tools that let us look at a wave's harmonics in this way are called spectrum analyzer, which are desendants or cousins of the oscilloscope which plots the Amplitude of a wave (vertical axis) against the time axis (horizontal axis).

Note the name spectrum here is not used in vain. Because as you see in the picture, the graph actually shows us a spectrum of frequencies, with spikes where overtones occur in the wave. This is very much like the spectra we get when analyze chemical elements and compounds to get to see which frequencies of light they emit (or absorb i don't remember) in the visible light band of the electromagnetic spectrum. Very much in the same vain, the color of an object is also those portions of visible light that are reflected or emitted by it.
Each object has its own spectrum (ie, collection of frequencies that make up its color) In the case of material objects , the frequency is that of electromagnetic waves, in teh case of sounds, the frequencies are those of accoustic pressure waves in the air, and in the case of synthesized sounds, they are frequencies of an electrical current signal.

Therefore, as my friend has noted, it does make perfect sense to use colour when describing a musical sound.

beschreiben timbre

Often people try to characterize types of timbre quality as fat, deep or in terms of having colour.

but calling the sound of 3 overlapping oscillators "Fatter" just because there are more sound sources is a bit inaccurate. It seems color is naturally suited to describe differences of timbre between instruments.

A friend once observed that "colour" was a pretty natural choice of metaphor when describing the timbre of a sound, refering to the fact that the presence of multiple frequencies is at play both in the visible light waves we call colour and in the waves of musical tones.

In general, the timbre of a given musical sound (indeed any sound) is determined by the harmonic content of the accoustic pressure wave. OK statements like this are deceptively simple (save perhaps for the term harmonic to some readers) but they contain within a great deal of information. Let's simplify this statement and explore the concepts it encapsulates.

For starters, if the term "harmonic" sounds confusing we can do without it for now, because in any sound wave there are two components (among others) that make up / describe the qualities and characteristics of the wave: Amplitude (the loudness of the wave over time), and its frequency (the number of times the periodic waveform is repeated in a given unit of time). The latter , frequency, or rather a multitude of frequencies - combined together (added, interfering) to form the Waveform of the sound , ie the way the wave's amplitude looks during the time of a single cycle of the wave - make up the harmonic content of a wave.

I would also like to add that when I speak of waves I shouldn't only be speaking of accoustic or sound waves, which because they travel through air contracting and expanding it, I like to call by their other physical name, pressure waves.
There are also electric waves. And much of what gets said of the sound produced by material accoustic instruments , also applies to waves of electrical current, voltage waves , or electrical signals, streams of them. These are usually produced not by material accoustic instruments but by electric circuits that generate waves of different types and that modify them in different ways, (this is called synthesizing) and then drive loud speakers which convert the electric current waves into actual sounds that we hear (this is called reproduction). The electric waves themselves could also be analogs of wave information initially produced as binary data that describe all the properties of the waves produced, from waveforms to full performances.
