- 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?
Sure, the position I'm coming from is that there is a varied and subjective experience of music, but there is clearly a shared consensus of what is good. That we all share common characteristics of auditory and musical experience because we are all human--not that we all experience music the same way or have the same appreciation of individual songs, but that our experience of music has similarities due to our shared human nature.
So if I hit random piano keys with my hands a few times and call it a song, the consensus of music listeners would be that Beethoven's Fur Elise is a better song. I'm saying that it seems evident to me that there is something objectively different about those two "songs" that in tandem with human nature makes Fur Elise appeal as the better song to the general consensus of human music listeners. (of course outliers could enjoy my random chords more).
So where we might be conflicting, is that I see something objective behind what makes a "good" song by the consensus of human nature. I agree that there are many cultural factors at play as to what is popular according to mass culture. But if song quality is related to something objective, and the general consensus is that the best classical artists are from over 50-100 years ago, why would the rate of "great" classical songs have declined while there is as much or more opportunity to compose classical music as ever? Through the internet, we also have the quickest dissemination of music ever (so it seems unlikely that classical music fans would be unaware of current composers who are performing as great of works as Beethoven or Mozart).
More simply, I'm viewing songs as concepts. So like "you can't reinvent the wheel", you can't reinvent Fur Elise. So it's not that there are not skilled composers currently, but that there is very few remaining concepts (songs) for them to invent. Just like you could reinvent the lightbulb, but you wouldn't get acclaim for that because Thomas Edison already did that.
I agree with you that this is a difficult idea to prove, because what I am claiming are self-evident propositions--upon examination--are very complex. But I done't see a way to break the observation down further into simpler if/then arguments.
First of all, Beethoven's "Für Elise" isn't a song, it's a bagatelle; let's get the genre right. (The previous sentence also demonstrates the proper use of the word "genre", by the way.)
The rest of your comment is just a reaffirmation of your confusion of mass culture and culture tout court. I (might) agree that mass-culture's greatness-producing capacities have plateaued, but I don't look to mass culture as a source of artistic greatness, so I don't really care.
If you studied music in sufficient depth, you'd see the possibilities for ...
