My conclusion, part 2.
The traditional word "fidelity" (not to be confused with "fealty") denotes the normal human inclination to shape one's own conceptions, feelings, judgments and acts of will, in light of those of another. Society's fundamental coherence and form have always depended crucially upon fidelity.
Fidelity can in some cases extend to the ability to see 'through' the eyes of another and to hear 'through' the ears of another. This is where the fine arts come fully into play.
Fidelity depends entirely on the normal human ability to form, develop and maintain subconscious 'models' of others. This is thought to be precisely where narcissists and psychopaths are disabled (e.g. A. Damasio, 1994).
To use today's parlance, narcissists are incapable of emotional empathy. So how can narcissists engage in music creation? Obviously, they can't - not in any normal, healthy, honest way. That's why I advocate seeking them out and wresting their hands off our music, by whatever means possible. They just do not belong in music making of any kind.
Likewise, as neurologist Paul D. MacLean lamented, long-term over-exaltation of the intellect can lead to very similar empathic blindness; the resulting ineptness is what we typically mock and shun when nerds and geeks candidly try their hand at music-making. (Indeed MacLean speculated that since the human intellect is so prone to to this functioning-in-isolation issue, perhaps the human brain is destined to be a Darwinian blind alley.)
So in this day and age, when "the rise of the small" is all the rage and all kinds of moral and social dysfunction are touted as the new norms, it's no surprise to find that narcissists, nerds, geeks and "the new helpless" not only can hide in plain sight, but moreover are busy infiltrating many kinds of computer-based music-making endeavours in which they can masquerade as being musically competent.
Inevitably, since the highly-mechanised tools now available can - to a limited extent - stand in for and cover up gross incompetence in music-making, programme music for media has become what it is today.
Also, even today, centuries after super-geeks Descartes, Locke, Hegel, et al. blathered their barmy bilge in praise of the seeming sovereignty of the intellect, we still find those who advocate "educating" audiences in order that they may better understand, appreciate and enjoy the utter tosh dished up as "educated" music by academic geeks. Oh dear God Almighty, it's as if nobody's learned a damned thing from the abject failure and collapse of the dreadful Marxist-Leninist experiment in designing utopia. (Marx had been one of Hegel's students at Berlin University. Hegel was an intellectual fraud who plagiarised - and fatally bastardised - the ancient Oriental Taoist understanding of the dialectic, and peddled the result as his own doctrine of "the Absolute".)
If I may offer this as general advice (and if the vast majority of adept musicians will forgive me for stating the bleeding obvious, lol): it pays to bear in mind that no matter how much it may seem to be,
the intellect is not sovereign within the human organism.
