From Harmonic Ratios to Geometric Forms. A book about pure intervals, microtonality, the overtone series and the hidden geometry of sound. Each entry pairs a concentrated reflection on one frequency ratio with its interference pattern — and every ratio in the book can be heard on a free companion page.
