SIXTY SQUARE SPHERE: Tales from the Borough of Before
A Song Cycle in Two Acts
©2026 John F Sendelbach
This cycle did not begin as music. It began thirty years ago, with my hands.
For three decades I have built geodesic structures—cutting members, bolting joints, learning by failure and repetition the exact grammar of how struts and faces resolve into closed, standing form. That long apprenticeship was not, I now understand, only the building of objects. It was the building of a regime—a constraint system learned so deeply that its rules lived in the hand before they were ever stated as rules. And within the last year, from inside that regime, a consequence became visible that had been waiting there the whole time: that the expansion of a polyhedron’s edges has no natural end. Every completed edge is another candidate opening. The procedure does not contain its own stop. I did not invent this. I discovered it—which, as this cycle will insist, is a different act.
Then, separately, along a different line of thought entirely, I found myself turning over the old question of parallel worlds—of variations that might “exist somewhere somehow.” I worked it back and forth until, one day, the obvious struck: the two things were the same thing. A finite rule generating an endless family of determined-but-unbuilt configurations is the possibility-space structure, rebuilt in steel. The metaphysics I had been chasing in the abstract, I had been holding in my hands for thirty years. This album is what happened when I overlaid the one onto the other and pulled the result up into the register of the song cycles that raised me—the ones that hide a rigorous architecture under a surface that rewards decoding but never demands it.
So the album is the narrative body of an inquiry, and the inquiry has a companion paper—Possibility Spaces, Formal Resistance, and Selected Realization—but let me first tell you plainly what the whole thing is about, because it turns out to be about its own making.
