A Textual Research of on Reproducing and Frequencies Detecting

Zhu Zaiyu not only developed twelve一tone equal temperament theory ,but also put forward a set of detailed drafts of pitch一pipes and their producing methods. Did those pitch一pipes given by Zhu obey the law of twelve一tone equal temperament?Many researchers have reproduced the pipes ,detected their frequencies but different results turned out. Basing on detailed analyzing on reason of those differences ,this paper discussed the correct reproducing method and steps and thus the conclusion that Zhu’s pitch一pipes was really a great achievement of acoustics in ancient China was deduced.
