As my patrons know, I made a last-minute swap of the theory essay this past Friday. And I remembered to update the notification sent to them! . . . but I didn’t update my post here. So 1) y’all know what a future theory essay will be about, and 2) the correct link is to “The Setting Bible, Part 1.” (The swap happened because what was supposed to be an upcoming essay turned out to span two, and I moved the first part up so as to get both into the same annual collection, rather than splitting them across volumes.)
