For reasons I’ll develop in a forthcoming post, I want to take a moment here to talk a bit about the Game itself as Hesse envisioned it. It emerged, according to his invented history, out of the fields of mathematics and musicology, as scholars found common patterns underlying the two disciplines—the structure of a geometric proof, let’s say, sharing the same abstract form as a Bach fugue or a Gregorian chant. Early on, the game was played with an abacus-like device with wires representing the conventional musical staff, and glass beads of different sizes, colors, shapes, and so on—thus the name of the Game—providing a more complex alphabet in place of simple musical notes. Later on, a formal mathematical script was developed; more scholarly disciplines took up the Game, finding their own abstract patterns and relating them to the musico-mathematic core ...
