Research On The Acoustic Characteristics Of Nanyin Pipa

Nanyin pipa is one of the important main instruments of nanyin,and it retains the relic of ancient quqi pipa.This paper takes the acoustic characteristics of nanyin pipa as the research object,and based on the acoustic composition of nanyin pipa,carries out physical analysis on the measured data of nanyin pipa and contemporary pipa.By analyzing the spectral characteristics of the nanyin pipa and the contemporary pipa and combining the variation of the harmonic amplitude of the two instruments during the vibration process,the acoustic characteristics of the nanyin pipa are revealed through comparison.Nanyin pipa players and their musicians believe that nanyin pipa has a short aftersound,dark tone and soft sound effect,which is the best,and most prefer the middle and bass tone of nanyin pipa.The tone aesthetic tendency of nanyin pipa is related to the lifestyle of local people.The aesthetic choice of nanyin pipa also determines its unique structure,which is different from that of contemporary pipa.
