Let's take a real example.
If you look at a mass in Chigi, say the Ockegham L'homme arme, the placement of the text isn't something you can read off the page. Indeed some of the mass text seems not to fit the music at all. How you make sense of that has all sorts of consequences for the way the voices interact, and the resulting rhythms and harmonies.
Some, indeed most, performers sing the music so as to maximise consonance, and to make the whole cohere and blend in a sweet way. And that's based on an ideological presupposition about what sort of sound reflects renaissance ideals as much as anything else. The music in their hands sounds safely predictable because those ideals are really very similar to late Baroque and even classical ideals.
What I'm trying to do is expose that for the presupposition that it is. And scrutinise it.
I want to suggest that what's going on is nothing short of an appropriation, an occupation, a colonisation, of the (early) renaissance by the modern.
My line of thought really comes out of trying to make sense of what Bjorn Schmelzer and Rebecca Stewart and their pupils do with the music, and the ensemble The Sound and the Fury.
