Discourse The Effect Of Air Velocity And Lip Seam Size On The Sound Bamboo Flute

Bamboo flute is an edge tone wind instrument that is excited by the air impacting the edge of the hole on the bamboo flute.In the process of exciting edge tone,the lip seam plays an important role in mediating and regulating.Therefore,from the perspective of performance,the player's air and lip seam have an important influence on the sound played by the bamboo flute.The principal part of this paper is divided into three chapters.Based on experiments and applications,through acoustic experiments and data statistics,as well as analysis of spectrum and musical examples,combined with the author's own playing experience,from the two aspects of Air Velocity and Lip Seam Size,to analyze and discourse the effect of the both on the sound of bamboo flute.The first chapter is divided into four sections.The first section mainly introduces the shape,sound principle and acoustic composition of bamboo flute based on the research results of seniors in the industry.The second section mainly explains the role of air and lip seam in bamboo flute performance.Sections one and two are important theoretical and practical foundations of the full text,and are used to draw the arguments of this article.The third section mainly expounds two important concepts in the title of Air Velocity and Lip Seam Size.The fourth section mainly explains the five factors of pitch,intensity and timbre etc.of bamboo flute sounds,as well as the explanation and discrimination of the terms of each element.Sections 3 and 4 explain and explain the three terms “Air Velocity” and “Lip Seam Size” and “Sound of Bamboo Flute” involved in the title of the thesis,limiting the scope of the article.There are four sections in second chapter.The main content is the experiment and analysis of the relationship between Air Velocity,Lip Seam Size and Sound of Bamboo Flute.The first section mainly explains the purpose of this experiment: measure the air velocity,lip seam size in different playing methods,and record specific physical quantities for comparison and analysis of the experiment.The second part details the experimental methods,implementation sequence and test items.Sections 3 and 4 are important chapters of this article.The third section mainly includes the results of the experiment,as well as a comparative analysis of the experimental results,and draws the experimental conclusions.The fourth section is an analysis of the experimental conclusions in the third section,and combined with the author's own playing experience,puts forward several performance suggestions.The third chapter consists of two parts.The first part introduces the bamboo flute solo “Flight of the Chinese Partridge” from the two aspects of the composer Mr.Zhao Songting and the artistic conception style of the music.This chapter focuses on the second part.Using the experimental conclusions drawn in the second chapter,analyzes the two difficult part in the piece “Flight of the Chinese Partridge” respectively.
