a participatory culture makes the notion of a skill-level hierarchy more apparent and well-defined
Not so. Fetishizing extreme 'skill', virtuosity, stardom etc. is a marker of a consumer culture, not a participatory one. One needs only look at what may be the earliest comprehensively-documented instance of a mostly- or entirely-passive musical culture, namely the elite dramma per musica a.k.a. opera seria, to be sure that this is the case! (This is something that people were keenly aware of at the time - which is why opera was eventually reformed to make it more "natural".)
"composers writing for composers" is a way of describing a participatory culture (which suggests that its use as a derogatory description is pathological).
Well, to the extent that they are indeed engaging in such an activity for the sake of participation, this is certainly true. But it's quite doubtful to me that even the "anti-populist fortress" of academia (as you put it later in your comment) can escape its own sort of consumer culture-ish dynamics. In this case, of course, such dynamics involve, not so much 'compromising' for the sake of mainstream popularity, but precisely the striving for some peak of perceived 'skill' and stardom (as judged e.g. by influential critics, patrons/funders and other outsiders), even when this is to the detriment of the overall interestingness and breadth of the participatory process.[1]
If so, this may be a case where all we can do is pick our place on a deeply uncomfortable tradeoff - since neither of these processes seems to track the values we would prefer! But a combination of the refragmentation you point to later on[2] and an increase in influence from the more self-consciously "low skill" and "DIY" subcultures seems to offer the best hope for improvement. Which is paradoxical indeed if you simply assume that these "DIY" subcultures must be "mass" cultures and thus cannot possibly help further an "elite" tradition.
[1] A further issue compounding this 'Moloch' problem, is that - much like J.S. Bach who thought of the Lutheran God as being his audience - most "academic" composers nowadays seem to be making music to worship Ra. The Lutheran God very possibly does not exist, but everyone has experienced 'Ra' in some form, and I for one don't think of Ra-worship as especially worthwhile, either artistically or in a broader social sense.
[2] (I had actually been taking this process for granted; I agree that the increasingly-consolidated, capital-intensive, "mainstream" music industry is obviously not a force for increased participation!)
Not so. Fetishizing extreme 'skill', virtuosity, stardom etc. is a marker of a consumer culture, not a participatory one.
Here you have once again done something that you have done a number of times before, which is to "round off" my meaning to something completely different from what I intended. A skill-level hierarchy is a completely different concept from the fetishizing of extreme skill, to the point where they are almost opposites: extreme skill will tend to be fetishized (as opposed to admired) in situations where ordinary skill is not ap...
