| Xu Yangyuan’s "Tube Colorimetry" has nine sections,including the origin of tube color,control,notation,palace,28 tone name system,silver character tube,killing sound,flute system and related problems differentiation,examination errors,the content is very rich.Taking this work as the research object,author puts "Tube Color" in the historical change of wind music palace tone from Jin to Ming and Qing Dynasties,and discusses the related music issues such as change of keys,melody transgression,killing sound and using sound,so as to clarify the change of tube color since Tang Dynasty.Full text consists of five chapters.The first chapter mainly introduces Xu Yangyuan and the content in "Tube Colorimetry".Xu Yangyuan was born in the 23 rd year of Qianlong and died in the fifth year of Daoguang.Completed in the fifth year of Jiaqing Dynasty,the one-volume "Tube Colorimetry" is divided into nine sections: origin,control,music method,change of keys,Yin Zi Zhong Guan,Killing sound Using sound,difference differentiation,flute system,and examination errors.It discusses many music problems.The second chapter mainly explains the meaning of Xu Yangyuan’s so-called "tube color".In its narrow sense,tube color means character spectrum,which is set up because of the fingerings of wind instruments,also known as tube chromatography,that is,the spectral form of fingerings,hole positions,tone names and law names corresponding to each other.Since many historical documents of pipe chromatography often explain music problems in the form of its characters corresponding to the killing sound in 28 tones since Sui and Tang Dynasties,further discusses the relationship between pipe color characters and the killing sound in 28 tones in the second chapter.In a broad sense,"tube color" is a comprehensive term with a rich name.In terms of the region of music it carries,it mostly refers to northern music.In terms of wind instruments,it often refers to the tartar pipe,flute and xiao pipe.It can be seen that "Tube Colorimetry" is actually a music book involving Musical Instruments,music,palace tune and many other issues.The third chapter mainly expounds the corresponding relationship between tube color character spectrum and Lv.Vulgar music "with the word sound",sound and word just match;And elegant music "to match the law",the law of many words,difficult to have a specific distinction.However,from the current situation of the loss of elegant music at that time,it is not enough to restore the ancient music by matching words with sounds,and only the existence of collocation rules can introduce the common and elegant.At the same time,elegant music uses more tones,and vulgar music highlights the use of tone.Although the positive tone and the lower tone seem to be two standards of different house positions on the surface,but in essence they are the juxtaposition of two scale structures.The fourth chapter mainly expounds the theory of palace modulation in the "Tube Colorimetry".The first section explains the functions of "Zhong Guan" and "Zhong Guan Diao",which are of great significance to the theoretical interpretation of the 84 tone system.Secondly,the theory of criminal tone is combined with the color spectrum of the tube,and the killing and using sound of the 28 tone are connected to further analyze the meaning of "criminal".The fifth chapter mainly combs the historical documents cited and reviewed in Xu Yangyuan’s "Tube Colorimetry".On the one hand,it explores the scholars’ cognition of Guan chromatic and the development of Guan chromatic theory.On the other hand,it explores the characteristics of Xu Yangyuan’s theory of tube color and the value of the book Tube Color. |
