"Lü"and"Lü":A Study on the Nomenclature of He Chengtian and Zhu Zaiyu's Theories of Musical Temperament
The musical temperament theory of He Chengtian,a theorist from the Southern Song Dynasty,has traditionally been referred to as"He Chengtian's New Lü(律)".However,based on analyses of relevant documents such as the Song Shu(Book of Song)and the Sui Shu(Book of Sui),as well as the meanings of the characters"律"(lü)and"率"(lü)in ancient musical temperament theories,a more appropriate name for He Chengtian's theory should be"He Chengtian's New Lü(率)."Zhu Zaiyu named his theory"Xin Fa Mi Lü"to emphasize the meaning of"mi lü"as it represents the value of Pi(π).The reason why He Chengtian's New Lü(率)became the foundational basis for Zhu Zaiyu's invention of"Xin Fa Mi Lü"is due to their shared understanding of the significance of"Lü(率)"in music.The terms"He Chengtian's New Lü(率)"and Zhu Zaiyu's"Xin Fa Mi Lü"are significant in constructing a Chinese discourse system for musi-cal temperament studies.
