A Study On The Performance Of Decomposing Chords And Their Variants In Duporf's 21 Cello Etudes

Jean-Louis.As an educator,Duport cultivated and influenced many violinists.His "21 cello etudes" are the early and practical etudes that have been handed down,and some of these works have been used in many of the exercises published in modern and modern times.For example,the popular published by the people's Music Publishing House in China,Professor Song Tao edited the cello course etudes diversity,the use of 9 works in this etude.Many of the cello techniques involved are still difficult in the contemporary era.In the analysis of this work,the author finds that the types of "chord decomposition and its variations" occupy a relatively large proportion,so this is the main starting point to explore the role of these types in the whole textbook.As well as its impetus to cello development,it provides a complete introduction and analysis of Duport's teaching materials for cello players.In cello works,many difficult fragments are composed of decomposing and mixing string type and its variant with various playing techniques,and often become the most important and difficult points in the whole work.Through the reading and analysis of Duport's textbooks and the performance and induction of etudes,the author tries to find out the rules and practice methods of "decomposing chords and their variations".In order to play cello works in the future meet the relevant pieces can be faster,better understanding and practice.In the domestic literature on Duport's 21 cello etudes,we can find out the technical research on "finger method" and "thumb grip".The first article is published in the Journal of Tianjin Conservatory of Music(Tiana),the second issue of 2006,Wu Xiuyun's study of Duport cello finger method;Another is a revolution in the 18 th century cello performance by Wang Dingzhu,published in the Journal of Nanjing Academy of Arts,No.01,2009-interpreting Duport's "thumb grip" technique in 21 cello etudes.But there is no thematic study on the various playing techniques involved in "decomposing chords and their variations".Therefore,this paper takes this as a starting point and classifies the decomposed chords and their variations in this set of etudes by analyzing and categorizing the phonological types of the disassembled chords and their variants in this set of etudes.In combination with Duport's works on cello playing,the corresponding playing techniques are described in as much detail as possible.The first chapter introduces 21 cello etudes,the second chapter is the analysis of the characteristics of 21 cello etudes,and the third chapter is the performance practice of 21 cello etudes.
