I have been thinking about this for a while but have not, as yet, written anything about the matter but I have been considering how defenders of tradition, or The Great Tradition, who may have all sorts of things about the timeless and transcendental nature of serious music (or "serious music" depending on your perspective) have four core arguments (or fallbacks) on why some music is more worthy of consideration than others. Much as I love a lot of music that has been situated in the "tradition" I have not been able to avoid thinking about how there are four arguments against American popular song and dance idioms as "serious" music that were essentially formulated by Theodor Adorno that have been taken up by men who might otherwise vilify Adorno as one of the great villains of the 20th century where music, and specifically classical music, is concerned.
Without trawling through the half dozen books in which Adorno presented his canards, I'm opting at this point to merely present the canards themselves. Specialists will most likely already know where they are found!
