Architecture, Techno, Sacred Sites and Religion ii

The eastern buildings are based on perfect symmetry and forms such as Ankor Wat and the pyramid at Giza which are intended to be magical talismans to ward off evil and to spread good fortune emanating from above. To the eastern mind, spiritual power is constantly coming down and in here. To the western mind spirit is up and out there. Hell is down here.

Eastern music is often of a ritual nature and for the gods. The Indonesian gamelan might play all night for the benefit of the village with no one attending the concert. African music is often a ritual for the gods and there's no thought of making a pretty sound for people to listen to.

Architecture, Techno, Sacred Sites and Religion iii

Eastern sacred music is often based on perfect cycles which repeat indefinitely though usually additive (5+3) and not usually divided in half as in (4+4).One article I read said that if one were allowed to make sweeping generalizations, the eastern position comes from a fear of foreign people and ideas or at least negative spiritual influences and a willfull denial of the death of the individual personality wishing it to continue after the death of the body in some imagined magical relationship with geometric perfection. About 1/4 of westerners explored the world in the age of exploration and seem to embrace the alien other/foreign neighbor and ideas or at least are willing to entertain them and therefore must deal with both the positive and negative aspects of admitting the enemy.

However, not all eastern music or easterns fit this generalization and neither do westerners. As if a fine line could ever be drawn. Another point was that symmetry in art and music usually comes only after the establishment of city states. The Mongolian shaman riding on horseback playing his spike fiddle took his aesthetic from the natural environment unconsciously.

Trees, mountains and rocks are not perfectly symmetrical and neither was his musical form. I imagine the Nomadic aesthetic of musicians in the deserts of Africa and Arabia are assymetrical as well.This is also related to Japanese music which was purposefully/consciously assymetrical. This was desirable to Zen Buddhists (those that didn't denounce music entirely) because the surprising changes caused by extreme assymetry represented egolessness to them.

Music That Accelerates From 0-60 p.7

Where do we expect to find symmetry in music. Actually, it seems that the primary place it is located is in the scale and often its tuning. There really aren't that many examples of reversible rhythms except at large levels of the rhythmic structure or melodies except with Bach and such, whose music is definitely for the mathematically inclined and not really the general fare even among Classical or Baroque composers.

Arabic scales known as Maqams and the gamalen's colotomic structure produce very symmetrical scales and rhythms. Two very beautiful musical traditions.

It becomes very obvious that every scale you can play also has a rhythm associated with it when you look at it constructed on a circle with the unison and the octave at the top in the same location. It’s manifestly apparent that some of the Arabic scales have notes which are half-flat or quarter tones for reasons of visual symmetry. It seemed to me unusual that the starting note for many maqams was not the one on the axis of symmetry.

Usually, it places the 1/4 flat on the 6th and/or 7th. That was interesting to me because the seventh degree is the one played microtonally flat or “blue” in Blues, Jazz, Rock and African as well, since that’s where Blues and Jazz comes from primarily. The seventh is often microtonally inflected in the Classical music of India also.


The form of a piece of music is another place where we often find a little symmetry. Beethoven and others were of the opinion that if you are writing a long piece then the beginning goes nowhere fast so you are alerted to the fact it's going to be a longer composition and likewise the ending needed to match the beginning in size somewhat and also relate to the scope of the entire piece.


Jazz tunes play the head, improvise and then return to the head. If the head is short, they play the head twice and the ending twice. This is a kind of symmetry without going to the extent of playing the theme backwards at the end which we don't expect in our tradition.

Symmetry is actually rare in nature except in the faces and bodies of animals. Trees, lakes, rivers, mountains etc. are not symmetrical. Music which does not have the symmetrical elements previously presented has the aesthetic of the nomad not seeing many faces or symmetrical buildings who often lives alone closer to nature and derives his aesthetic from that.
Contemporary composers could write more inter locking rhythms because it creates a smooth rhythmic surface without leaving any holes, just like a beautiful face

Some aestheticians say the reason we are all so concerned with beauty in art and music is because we don't live close enough to nature. We yearn for it and try to create it. I tentatively add that we may be trying to create it in our own image.

Perhaps a reason to use self retrograding rhythmic structures similar to palinromes in literature such as "A man, a plan, a canal. Panama." is not because of a need for symmetry. It's because the retrograde implies a desire to go backwad in time perhaps to a golden age. This is a little regressive however.
Another interpretation is that its a bit revolutionary. Anagrams/permutations imply an even more revolutionary philosophical standpoint.

Then there are philosophical considerations. In the Heterotopia where we actually live, we have to honor the interests and aptitudes of the composer, the performer and the audience. We cannot mirror a utopia in which we do not believe.

One based on elitism, ageism, classism, sexism and all. In my case, I'm a composer whose interests and aptitudes cluster around symbols. As such, when made aware of the fact the very notes themselves have symbollic meaning, these symbols are of interest to me.
