Acoustic Measurement And Research Of Dongbula In Xinjiang,China

There are many ethnic minorities in China,and Xinjiang is the region where a large number of ethnic minorities live.In the northern part of Xinjiang,there is a relatively concentrated distribution of plucked musical instruments Dongbula players.Its traditional musical instrument culture is closely related to the local historical environment,cultural environment and folk customs.The music culture produced in different regions is also different but colorful.The thesis analyzes and learns from historical data left by predecessors,filters and collects the data,and collects Dongbula's audio.At the same time,combines the core thesis of Dongbula's music culture and acoustic measurement to analyze the historical source of the plucked musical instrument Dongbula together with its acoustic quality,problems encountered in measurement analysis are explained in the thesis.The process to obtain the acoustic data of the musical instrument is very important.Firstly,the measurement process is explained and analyzed,the measurement object is selected,the measurement environment is selected,the recording staff,and the specific operation process.The above-mentioned four key points are finally used to achieve the purpose of the measurement.Because of this,the measurement system got corresponding data on the acoustic quality of the measuring instrument,and the acoustic data achieved could be more accurate,which also reflects the essential requirements of musical instrument acoustic measurement.The research thesis can be divided into the following four parts:Firstly the introduction.this section summarizes the references and research results related to Dongbula.Secondly,based on the origin of Dongbula,music,shape,and performance skills,a comprehensive analysis of the plucked musical instrument Dongbula was conducted.Thirdly,a brief overview of the musical instruments acoustics,which leads tothe significance of acoustic measurement experiments on plucked instruments;after that,analyze every vocal system of Dongbula,analyze and study the tools,processes which relate to audio measurement,and environmental factors which may ariseapter,the author will also explain the external conditions of the recording equipment,recording environment and the choice of performers,this will lay a foundation for the subsequent writing of the article.The fourth chapter of the thesis will mainly focus on the acoustic measurement experiment of the plucked instrument Dongbula.Then,the collected audio data will be measured by professional acoustic measurement software to obtain data results.For better comparison,Dongbulas with different texture and structure will be used as measured instruments,and the audio data will be collected and measured with open strings Dongbula and pizzicato technique.Finally,the plucked instrument Dongbula will be analyzed with the waveform diagram,spectrum diagram,and harmonic column data.The fifth chapter,based on the consideration and research of Dongbula in the early stage,from the perspective of inheritance and development,put forward prospective view,and provide suggestions for better inheritance and development of musical instruments.
