My take, again, is that beauty properly considered has an aesthetic element that can be disconnected from element of "right" or "wrong."
Ave Maria is glorious, but breaks a number of commandments in its being totally off on the theology of Mary. Is
Ave Maria beautiful? Yes; the melody is beautiful, the instrumentation is beautiful, the voices are beautiful--aesthetically considered. Is it beautiful, in terms of "right" or "wrong?" No, it is quite ugly in that regard.
Is a worldly, pagan, God-hating runway model beautiful? Yes. I mean, why else is she a runway model--in an aesthetic sense. Is she beautiful, in terms of "right?" Hardly, not having been cleansed by the blood of Christ, she is quite ugly.
Since Christ is Beauty Incarnate, since Jesus Christ is Beauty with a capital B, since all creation finds its end in Him, since he sustains Creation, since he partook Himself in Creation, since as it were the Father created by refracting all things through the eternal begotten Son, (think, Pink Floyd
Dark Side of the Moon album cover), we find laws of beauty. Because Jesus= Beauty, there is objective beauty. This is why, presently, only one person on earth is the most beautiful person on Earth, and
only known to God (it isn't me, that I know. Beside the point.) As I said, the circle of fifths, the Hz frequency between notes, the fact that a Major chord must lower the pitch of the third note in the chord to ensure it sounds in tune, that is to say, in God's providence, a major chord with three notes perfectly in tune sounds dissonant, but strangely, one must slightly lower the third pitch of the chord. This shows, it just has to show, that there is an objectivity to beauty, but we know that all beauty is straining to glorify the Son and finds it basis in the sustaining of the Son. If a pagan were to change the lyrics to
Amazing Grace to be horrifying, we have to say from a musical standpoint, according to the laws of music, it is beautiful. Yet, it falls fall short of glorifying the Son and in this sense it is ugly.
In Christ, the "aesthetic" realm of beauty and the "moral" realm of beauty perfectly coalesce. Ultimately, what has precedence is the "moral/spiritual" realm of beauty. And yet, there is a very close connection between the two realms of beauty. Heavy metal music tends to dissonance, discord, walls of sound pulsating but without direction, without tonality. Is it a coincidence the lyrics tend to be dark, hateful, spiteful, etc? But while there is a close connection, there is a separable connection. Heavy metal music might have Christian lyrics to the core. But we sense the ill-fittedness of this arrangement. The aesthetic realm is not fitted to the moral realm.
And so any judgment by a Christian of art must be nuanced. First, 1) How does this glorify the Son in terms of revelatory content of the piece (is it painting of a couple copulating? Likely, "Ugly," in the moral sense. Do the lyrics uplift Satan? Burn that trash) 2) How does this accord with the principles of beauty known since the ancient Greeks: proportion, symmetry, etc, which have analogues from architecture, to painting, to photography, to interior design, to music to the principles of tragedy outlined by Aristotle and of good narrative, etc.
Back in the day, good art was that which imitated, reflected nature well. This seems a decent standard. We could also think of good art as that which evokes virtue-bringing emotions, habits, considerations. That's fine too. Ultimately, I think that beautiful art transforms, not merely imitates, nature. Just like a poem messes up syntax to raise the level of spoken word to an almost heavenly level, good visual art, for instance, takes God's beautiful creation and "disorders" it to "order it" anew. Artists reflect God by making, as God once made. But we use existing materials. But existing Creation is shot through by reflecting God's glory. The heaven's declare, do they not? That it both brings us to Jesus Christ, and does so by straining to accord with the eternal principles of Beauty inherent in all things, this is what good art should do.
Non-Christians can without knowing create amazing, God-glorifying artifacts. They have the law in their heart, natural law, and they have the God-given ability to know what is beautiful.
Finally, I want to add that there is an internal mechanism given to man by God that God uses to allow men to appreciate beauty. Man has the ability to be dazed, shocked, made speechless, by beautiful vistas in creation, but also beautiful paintings, beautiful songs, beautiful people. This can ground any theory of aesthetic judgment/taste. Having established there is a metaphysical basis for objectivity, because Jesus Christ is Beauty Incarnate, and created a beautiful Creation; and having established the obvious point that the fact we have a word "beauty" means God gave man the ability to take in that which is beautiful; so there is as it were an organ, a mechanism in each man and women to "get" that something is beautiful; THEN the category of taste comes in, as I pointed out earlier.
Sin disorders our sense of what is beautiful. Sin makes people think that what is aesthetically ugly is aesthetically beautiful, and what is morally ugly is morally beautiful. So, we rely on people trained in painting, or art, or sculpture, or photography, to train our tastes. Humbly, we must admit that our sense of what is beautiful is not the standard. Jesus Christ is the standard. And we must seek to learn, by looking at 1) concensus a) both through time and b) contemporary consensus and 2) by going to a) experts in a field and b) our own experiences .. . . Thus, one can become a gifted sommelier in a similar way one becomes a gifted critic of art.
Finally, I want to add that this "sense of the beautiful" is like "common sense." This category of common sense, commmon knowlege, has explanatory power for why certain things should be done, why certain people should think certain things, and is accepted widely. Likewise, Ploutos is searching for a ground to say this genre is better than that genre. I would appeal to the "common sense of the beautiful," and say that while sin can disorder it, and there can be objections, on the whole
consensus is a fine guide to determining what is beautiful. I can say that certain tribal dances are beautiful in a restricted or limited sense, but do not attain to the sublime, ecstatic expressions of something by Mahler or Beethoven. This isn't ethnocentrism. It isn't subjectivism. I can appeal to common sense of beauty; by common experience of Mahler, in contrast to the common experience of tribal drumming. Etc.
So there is certainly a strong
subjective element. But this can not stop a discussion.
https://www.beeradvocate.com/beer/top-rated/ on this website, Kentucky Branch Grand Stout is the highest rated beer. This is for no other reason than that thousands of beer drinkers have evaluated all the beers, and in their trained palate, trained by tasting thousands of beers, they have collectively agreed that it is simply an amazing beer. Some people may rate this beer 1/5. This means that they have bad taste. Objectively, they need to learn that Kentucky Branch Grand Stout is a better beer than Budweiser. So too, if someone says that a certain Bach fugue is 1/5, we can train them, point them to the "beer advocate" of musical consensus, and show them by pointing out the technical expressions, the emotional evocations, the historical feeling, that Bach is superior to this or that.
