Tone Row's Study Of The Uyghur Twelve Mukam

This paper chooses the 2nd version from the three issued Twelve Mukam of Uyghur versions as the research subject, using the demonstrative method of ethnomusicology and the advanced prevailing sound-measuring technology, measures the realtime pitches of tones that make up the basic tone rows of the Twelve Mukam of Uyghur, and concludes its characteristics of the tone degrees as follows: 1. In the tone rows of Twelve Mukam, the tone generally has no less than seven tone degrees. 2. In each tone degree, degree I and degree IV are the most stable ones while degree III is the most unstable one. Degree V,degree VII,degreeâ…¡and degree VI are relatively unstable. 3. There are a large number of one quarter tones and neutral tones and they mostly appear in degree III, degree V and degree VII with the form of semi-sharp. 4. Moving tones fall into three categories: appearing together with one quarter tones; appearing in the specified degree III, VI and VII; appearing in the downward melody. Generally, they move within the range of minor second, they reach minor third at most. And most of them move from the higher to the lower. 5. Both the stability of tone degree and the positions of one-quarter tones and the moving tones have relation with the first tone of the mode. And the following aspects form the tone...
