For the first time, each screen starts coordinating with its neighbors to figure out how to fit the themes together in Mozart’s tightly constructed fugue. The instrumental parts represented by each screen keep rearranging themselves in ever-more-accurate approximations on a repeating loop. This loop grows from a short 10 measures to reach the full 32 measures of the final coda, as tracked visually on the left of the screen.
