thesis
Let m be a modulus and s₁…sₖ a list of steps applied cyclically. The residues mod m are purely periodic with period dividing k if and only if Σsᵢ ≡ 0 (mod m). That single fact governs a drifting table of eleven, a curve on a sphere, the scale of every rāga, the standing waves in a room, and the reason an unaccompanied choir sinks flat. Everything else is the theorem in different clothes.
what it does
- The orbit 0,3,6,8 belongs to the partition, not to eleven, ten produces it too
- Every rāga, thāṭ and maqām is a solution of Σdᵢ ≡ 0; the maths was already there
- The comma pump: I-vi-ii-V-I in pure intervals lands 80/81, −21.51 cents, forever
- 0,3,6,9 is the most elegant orbit and the least musical. A finding, not a defect.
what it does not claim
Section 9 is a ledger of every error made in producing the work, eleven in a single session, several of which would have shipped had the figures not been rendered and looked at. Kept because a record showing only successes is not a record. And the standard the document sets itself: a coincidence is evidence only if you know how many coincidences you looked for.
