荀勖的音乐声学研究

Research on the Music Acoustics of Xun Xu

通过对《晋书》所载荀勖“笛律”的分析,以及按照荀勖“笛律”制作的“泰始笛”,并推衍至初唐吕才“尺八”,以及匀孔的汉魏长笛的制作验证,证明荀勖于公元274年之前研究笛律所涉及的开管和闭管,以及闭管律管同开管笛管之间的管口校正问题,是完全正确的。因此,荀勖当是世界上最早研究开管的笛管,同闭管的律管之间音程关系,以及管口校正等音乐声学难题之人。荀勖笛律对后世之笛箫制作产生了不小的影响。本人认为,今日若能找出荀勖“笛律”所制的“泰始笛”,同今日箫笛制作之间的异同,无疑有益于今日箫笛制作研究的进展。

Through the analysis of Xun Xu's"Di Lu"in the Jin Shu and the research on the"Taishi flute"made according to the"Di Lu",it has been proved that Xun Xu's research on the open-tube and close-tube of the flutes before 274 AD was completely correct.Therefore,Xun Xu was the first person in the world to study the interval relationship between the open-tube and the closed-tube as well as the problems of music acoustics.Xun Xu’s“Di Lu”had a great influence on the production of flute in later generations.In my opinion,if we can find out the similarities and differences between the"Taishi Flute"made by Xun Xu's"Di Lu"and the modern flute,it will undoubtedly benefit the research progress of today's flute production.
