Discovery of Musical Equal Temperament in China and Europe in the Sixteenth Century

Author: Cho, Gene Jinsiong
This study provides little-known mathematical, musicological and scientific facts regarding the discovery of musical equal temperament, and narrates the circumstances of the discovery in the historical and cultural contexts of the period (mid 16th to early 17th centuries) which, in turn, is placed in the intellectual chronology of the Eastern and Western worlds. By offering documentary evidence and information not found in Western publications, the book invites the reader to see the mathematics of the equal temperament and its discovery in an entirely new light.


“The author is fully conversant and equally at home with both the Eastern and Western cultural and scholastic environments. He therefore possesses a unique qualification as an objective scholar to address and assess the issues by drawing from his wide ranging knowledge in cultural history and scientific philosophy of both hemispheres…. Without doubt, the present work is one of the most thorough, convincing, and absorbing of the documents this writer has read in recent years on the topic….demonstrates his tenacity of research, the credence of finding, and his sound discernment.” – Dai Nianzu, Senior Fellow, The Chinese Academy of Sciences
