- Do you agree that from experience and observation, we can tell that certain genres or fields appear to become completed?
- Does this concept or another concept best explain what is happening?
I would argue that you are taking a narrow view of what music is. The fascination with the collection and intellectual understanding of information, as well as an addiction to emotional impact is something that is characteristic of our culture. And of course the music produced by a culture will be a reflection of the mind of its people.
I recommend that you examine carefully the wide variety of functions that music (and art in general) has in traditional cultures. Emotional, medicinal, social, as an aid to memorisation (see the Australian aborigines or vedic chanting), religious and spiritual, war and discipline and the list goes on. It is an extremely complex, and actually not yet understood, subject. In my opinion what you see in mainstream art is the exaggeration of our cultural characteristics mediated by the ability to record, manipulate and reproduce 'art' en mass.
Sure, I didn't mean to take a narrow view of music, just to narrowly examine "newness" in music, which is a different question. I agree that music serves many purposes besides pop consumption of new songs or works. That is something I would want to explore further at some point.
I was aiming to understand the metaphysical question: is there is a limit to newness in music, and if so what does that imply about our universe? Could examining that question give us greater clarity in understanding the limits of other discovery or creation?
