“协和进化论”的立论依据来自“反应论”,说“协和是我们对声浪的一种特殊适应,那些还没有适应的为不协和。今日所谓协和音程,都曾经有一时期为不协和。协和是由不协和进化得来。人类对于并发的二音,起初都不能在脑神经中综合为一,几经磨炼以后始能。何以协和起快感,不协和起不快感?因一则神经对之已经适应,直行无滞;一则还未适应,阻碍很多。按协和进化律,凡不协和的音程,重复听百千万次以后, The theory of “Concordant Evolutionism” is based on the theory of “reaction theory” and states that “Concordance is a special adaptation to the sound waves of our society and those that have not been adapted are incongrities.” In today’s so-called Concordary Interchangation, there was a period of discontent. By the uncoordinated evolution of human beings for the concurrent two tone, at first can not be integrated in the cranial nerve, after a few temper can begin .How to reconcile the pleasure, uncooperative displeasure? Because of a nerve to adapt to it , Straight without delay; one has not yet adapted to a lot of obstacles.According to the evolutionary law of co-evolution, where inconsistent intervals, listen repeatedly millions of times,
