Acoustic Measurement And Research Of The Xinjiang Uygur Musical Plucked Seoul

The Uighur settlements in the east,south and north regions of Xinjiang are the core distribution areas of the plucked instruments,and the musical instruments are closely related to the local history,culture and customs.Their geographical features are also different.Plucked Dial has a wide range of sounds,but also very unique tone,so in Xinjiang Uighur region,occupy a very central position.This thesis analyzes the actual situation in Xinjiang by analyzing the research results of the predecessors and analyzes the musical instruments and acoustics of the plectrum in the Uyghur region by means of recording and combining the knowledge of musical instruments and music.In the process,inevitably will encounter various problems,this theory also made a brief analysis and discussion.The essence of instrument acoustic measurement is the application of measurement system to the acoustic characteristics of the instrument given the corresponding data.In order to obtain accurate measurement results,the measurement system analyzes each process.Specifically,the analysis includes four aspects: external conditions(related to hardware and software facilities,musical instruments,performers,measurement environment),The staff(that is,the worker performing the survey),the object of measurement(performance performed by the sound to the performer’s performance),the operation process,and the goal of data measurement is achieved through the combination of the above four points.The theory can be divided into four parts:First of all,it is an introduction.This part summarizes the conclusion of the study on the plectrum,and puts forward a brand new research perspective and research method based on the data collected by the author.Secondly,it simply sums up and summarizes the domestic and foreign documents and research results about the plucked ball,and analyzes the plucked ball synthetically from the aspects of source,music,shape and playing skills.Thirdly,using the experimental method,we analyzed and researched the measurement-related tools,processes,and errors that may occur in the measurement process,and found that when measuring the current data,it can be found that the surveyors still have certain cognitions Problems,but also need to further learn the knowledge of measurement tools;through the FFT mode to measure steady-state pitch,the length and the reproducibility of the measured data to further study and analyze the relationship between length and error;pitch and spectrum measurements As the basis,analyzes each function of GAMS software,points out the advantage that has by the measurement to the error monitoring and so on.In the fourth part,the waveform and spectrogram of acoustic dial recording are respectively described and analyzed.
