- 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?
It is difficult to judge at first, but it appears that some music genres (classical and jazz especially) have seen a radically slowed or non-existent output of significant works in recent decades
With all due respect, how would you know? Most people are so thoroughly ignorant of music that they can't possibly be expected to take notice of significant new works. (This is a general problem in many domains.)
As far as I can tell, the phenomenon you're noticing is simply that mass culture is not a process that optimizes for artistic value. But why should anyone have expected it to be?
The only reason that e.g. Beethoven has the mass-cultural prestige that he does is because he was grandfathered in at the beginning of mass culture, when it was seeded by elite culture. But mass culture eventually developed its own products, which have gradually displaced and eroded the prestige of the original "starters' kit" that included Beethoven.
Luckily, technology has made it possible to avoid relying on mass culture for access to culture. Beethoven may not be on TV but he is on YouTube, in abundance. (The name "YouTube" takes on some appropriate significance in this context.)
But people won't be able to properly enjoy this state of affairs unless they recognize that mass culture isn't a process for producing what they actually want (i.e. stop caring that Beethoven isn't on TV, when he is on YouTube).
All this is by way of explaining that, while you say "there's no one like Beethoven around", the idea that even Beethoven is "around" (present in mass culture) is mostly an illusion; and that a fortiori, you would not expect mass culture to have "noticed" his successors.
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 Beet...
