Research On The Characteristics Of Contemporary 10-hole Wide Range Xun

This paper focuses on exploring xun's principle of pronunciation,the principle of pitch change,and several problems in music.The logical procedure of its exploration is as follows: the first step is to summarize the previous literature and theoretical achievements.The second step is to master the knowledge of Musical Instruments.The third step is to verify xun's principle of pronunciation and the principle of pitch generation based on experimental data or practical experience of performance with acoustic theory knowledge.The fourth step is to combine theory with practice to summarize and sort out the objects to be studied and put forward their own opinions on the problems of music learning.On the principle of pronunciation,after reviewing and analyzing the previous scholars' conclusions on xun's pronunciation method,I draw the view that xun is an "closed-mouth" instrument according to the instrument structure.Based on this,I made a comparison between xun,flute and xiao equilateral edge wind instruments.I took xun's external cutting mouthpiece as the theoretical fulcrum,and used the airflow to stimulate edges and corners to drive the air vibration in the cavity to pronounce the rule.Finally,I drew the conclusion that xun is still an edge edge wind instrument.Next,I want to verify xun's tonal variation.First of all,the previous research results in acoustic theory are analyzed.On the basis of the experimental data as proof,through the comparison of the principle of pitch change between the tubular and canister instruments,the gas in the cavity and tube is divided into the effective vibration gas to determine the pitch and the sound transmission vibration gas for fusing the external air.After the exploration and verification of gas velocity,air force,airflow laser Angle,as well as the shape and structure,the same cavity structure and other problems,it is concluded that: under the condition of other factors stable,the effective vibration gas and the proportion of acoustic vibration gas in the cavity body can be changed by increasing or decreasing the xun wall area,thus producing a variety of tones.At the same time,I also made a strict inference to the partial ten-hole wide range xun's sound producing mechanism.When I understood my own acoustic problems,I explored several orchestra problems in my orchestra.First of all,the relevant theoretical achievements of the past as a reference,in accordance with the way of argument and speculative in-depth exploration.It is mainly expounded that the sound hole should include two aspects: the finger hole and the blow hole,that is,the sound hole is not equal to the finger hole.Secondly,in the research and archaeological work of xun,I should use the finger hole of xun as the title of several holes,because it should be consistent with the definition of the number of holes in other edge and edge music,so as not to mislead the readers' understanding of the research conclusion.Thirdly,this paper demonstrates several kinds of fingering arrangement design of ten-hole wide range xun,which can be divided into "fork fingering," "special fingering" and "half-hole fingering".In addition,according to the distribution of these three kinds of fingering in each kind of rhythm,the degree of difficulty and practicability of each rhythm after modulation are evaluated.Finally,on the premise of explaining the principles of all finger-toning andmodulation,I put forward the unified xun finger-toning and scheduling opinions.The whole article is based on experiments and supplemented by experience.Mainly from the longitudinal(all kinds of tune,shape of xun)and horizontal(similar edge edge wind instrument)two aspects,take the method of comparative analysis for research.
