Investigation And Acoustic Analysis Of Chinese Labrosones

Brass(Labial reed wind instrument,Labrosone)is an important part of Western orchestras.Brass has the characteristics of rich harmonic series,definite Directivity and high sound intensity,which is one of the factors to create the brilliant sound momentum of the orchestra.It is not difficult to find that the Chinese national orchestra lacks the whole set of brass instruments compared with the western orchestra.However,the lack of brass instruments in national orchestras also makes an important difference between them and Western orchestras.Therefore,it is very important to study Chinese traditional lip instrument systematically and explore its significance to the construction of national orchestra.This paper is to investigate the Chinese national labrosone instruments,sort out the types,distribution and use of Chinese national labrosone instruments,and carry out acoustic analysis on representative instruments to reveal their performance and acoustic characteristics in music performance,so as to provide support for the development and construction of national orchestras.On the one hand,to investigate the acoustic characteristics of the existing national labrosone instruments,on the other hand,to explore the possibility for the National Orchestra to join the labrosone instrument group.This paper reviews the types,distribution and use of Chinese labrosone instruments,and gives a systematic and complete overview of them.On the basis of the comparison and reference of Western brass instruments,this paper briefly introduces the development history of Western brass instruments,expounds their sound production principles,reveals their sound production science,and provides theoretical basis for the production of national labrosone instruments.Finally,the representative instruments are selected to measure and analyze,and the data are compared with the Western brass instruments to provide a theoretical basis for the improvement of the national labrosone instruments.
