The origins of the tuning system have never been described or found. This book analyzes the science behind A = 440 Hz as in today's tuning system. The question of why the key of C being the center of the piano is also researched. This book examines the effect of the magnetic field on earth and beyond on a day-to-day basis. The effect of the magnetic field may be able to be traced all the way to the galaxy and beyond. This book also contains evidence that the Mayan calendar may be connected to the magnetic field going into a new era.This third edition includes photographs of veneer and tree knots that suggest the tuning system can be observed for the first time in nature.
