your analogys are entertaining, but not wholly enlightening - at least not to me.
can you define classical music in MUSICAL TERMS - any hard and fast MUSICAL definitions?
Your question cannot be answered in simple musical terms/definitions, because what makes classical (erudite) music transcends purely musical definitions and theory. Now I will try to explain not only why it is so, but also why
it must be so.This explanation will also explain why certain popular pieces/songs become classics. Why we regard certain works of literature as “classics” and why certain works of art are highly prized over others. In short, I am going to provide an answer to the elusive question of what makes quality in art.
For this explanation to make any sense you must accept certain assumptions that to me seem completely obvious, but you would be surprised as to how many people ignore or even disagree with them.
We start with reality. Perhaps the most shocking fact about reality is that it consists of many levels. Nothing is as it appears. The simplest statement about reality can easily be proven incomplete (or even false) once you start to investigate it further. So the earth may appear to be flat but on further investigation we find that it is actually spherical. It appears not to move and yet it moves. And when you think you have figured out the way it moves, it happens not to be that way at all. And if you look at the whole thing from a different point of view (e.g the fourth dimension) the earth is not spherical at all, but looks more like a doughnut.
Then you have a person who appears to be someone. And yet on close investigations they turn up to be quite different. Some may surprise you so much that it will floor you.
People like to deride the occult and praise science, but what is science if not the ultimate occultism, since everything in science is explained by resort to things that are not apparent at all. Gravity, electricity, radioactivity, ultrasound, infrared, etc. are all occult. They belong to a different level than the level we are used to in our daily life.
And behind these levels there are other levels.
All this seem obvious to me. And yet there are people who will deny this. They wish to take everything at face value. For this people the earth is flat, because that is the evidence of their senses. They are literalists who can only experience the superficial and are satisfied with the very first level they can access. If there are other levels beyond the first one they are not interested, they don’t want to know.
Now consider a map of a town. The map is not the town. There are many more levels to the town that are not represented in the map. In fact they cannot be shown in the map. This is one of the limitations of models of reality (a map is a model of a town/territory). Models cannot show everything, they cannot show all the levels. Models also distort reality (for instance, a map is not the same size of a town). So if there are deletions, and if there are distortions, we are not dealing with the real, but with models of the real.
What few people realise (even though this information is freely available in any basic textbook of philosophy) is that we, human beings do not have direct access to reality. We experience reality through our senses, and our senses do not provide us with reality per se, but with models of reality. This is easy to demonstrate: all senses have deletions (we do not hear all sounds, we do not see all wavelengths), and all of them have distortions (vision is bidimensional – perspective is a distortion). So people who ultimately rely on their senses are relying on limited, distorted models of reality.
Then we have language, which is a model for what we experience through our senses, a model of the model. When we talk about reality, we are so far from the real product as to make the whole enterprise meaningless (but it is fun - which is why we persist).
Now if you followed so far, you are ready for the explanation.
Great works of art (which are necessary models of reality) are those who can reproduce the multi-level nature of reality. A great piece of music will have many levels. A poor piece of music will have a single, perhaps two levels. It is exactly this multitude of levels that allows one to listen to certain pieces of music over and over again and never tire of it, while other pieces will quickly overstay their welcome.
This is true of all the classics of literature: you can read them for the plot (one level), for the skill in language use (another level) for the implicit philosophy (yet another level), for the political message (one more level), for it power to evoke places/people/situations (yet another level) and so on and so forth. The author may have achieved this following plan, but I doubt it. Usually such superb multileveled works of art spring straight from the unconscious – itself a multilevel entity – and the author himself may marvel at his/her own work. Needless to say such authors do not just appear: they usually have worked hard on themselves, and at observing and encouraging their own multiplicity of levels. Their work is then a reflection of what they themselves are. Publishers may try to follow up the success of a legitimate classic by aping it. Usually it does not work, because publishers will believe that the success of the book is due to one single level (its political message, or its plot) and produce a single level imitation.
The same can be seen in Hollywood movies. Imititions fail because producers being usually literal people are unable to perceive the multiple levels and insist in picking one amongst many levels to reproduce in the imitation.
Likewsie with wine. Superior wine may have up to 30 different levels of taste.
Likewise with music. The music we call “classic”, high quality, superior, and the like, owes its superiority not to any musical principle, but to this single characteristic: to be able to convey many levels, sometimes - it could be argued – infinite levels.
Many of these levels may act in ways that are completely outside our sensual perception (think radioactivity: you cannot see or hear or feel it, but you will die of cancer if exposed enough to it). Music is vibration, and we are 90% liquid. Music may well reorganise our molecular orientation without us ever being aware of it and this is just one out of many possible levels). If such reorientation is positive we may experience the music as being superior and be inexorably drawn to it without being ever able to quite put our finger on the why. But even if this was proven as “the” reason for musical superiority (a certain vibrational pattern), to pursue this course would be to completely miss the point of multi-levels. Like the Holywood producer you would be reducing music to one single level again.
And how can one composer/interpreter create music in a way that it displays this multilevel characteristic? By continuously becoming yourself a multi level person. (This may explain the interesting case of Dr. Jekill and Mr. Hyde

).
What Faulty Damper is talking about (composing in the “style” of classical music) is actually a different thing altogether (the technical term being “Invention” – as in J. S. Bach 2 voice inventions.) Invention can be learned and applied but there is no guarantee that it will result in superior multi-level music. Yet invention is also very important.
Incidentally this is also one of the reasons why Charles Rosen in correct when he says that the composer may not know of his own intentions. There will be levels in a superior piece of music of which even the composer is unaware, but that a performer may notice and bring forth. In fact, Rachmaninoff used to say that Horowitz played his music better than himself. And he was not talking about technique. He was referring exactly to that: Horowitz could highlight aspects and levels of his music that came as a (pleasant) surprise to Rachmaninoff himself.
As with everything, this is just the tip of the iceberg (the other levels being occult

).
