No it is not an empty shell. It just reminds us of the limitations of human beings and exactly what gives value to them - music is a human activity and earns meaning through cultural and social value (or whatever you call them - politics if you want).That statement is an empty shell. It poses as having an "intrinsic quality", but has nothing else to offer than a superficial intellectual pose... attributed externally, of course.
Will that do as an explanation?
Guess not, so let me illustrate your point by applying your approach to something else: "Life has no intrinsic value - everything is attributed externally".
There. D'ya like that?
If I'm following you correctly, we should therefore get rid of life, right?
And no, you are not following me correctly see? I never said we should get rid of anything, neither life, neither music. That is your assumption, I never said that.
Just because something has no intrinsic value it doesn't mean one should get "rid" of it, or it is "bad". I pass no judgment on that.
The opposite it is what i want to convey:
because it has no intrinsic value, all value attributed is arbitrary and is made out of a convention and it is subjective, inherent to a culture.
what I'm saying is that in the extreme, ALL music is equally valid, beautiful, good or bad, depending on who is judging it and with which criteria. So, in the extreme all should be preserved and treasured. So it's the exact opposite of what you are assuming.
Imagine someone does a music with 2 chords and 1 note. And that one spends twenty years doing that and that it has a deep emotion while doing it. You might say "he is stupid then". I might say "no, he is the greatest! He did a very simple, yet meaningful craft and had a longlasting experience doing so, in a unique way!". Which of us is wrong or right? Any of us is wrong or right? Does it even make sense?
in the end all that matters is that someone had a beautiful experience.
