A transmission line based bowed string model is built by analogizing a vibrating string to an electrical transmission line and implementing the calculation for the frictional bow-string force given by a digital bow into a circuit. The performance of the proposed model is demonstrated by showing that the velocity of the string at the bowing point from the proposed model is consistent with that from the finite difference form of the wave equation for a bowed string by the digital bow.

Ajaeng is the bowed string instrument among zither instruments in East Asia, which has a circular form to date, and it has established itself as an important instrument in today's creative Gugak along with traditional music. Looking at previous prior studies, musical instrument studies have not been actively conducted due to insufficient data from musical history studies, and this study looked at the origin, form of musical instrument, and performance methods of zither bowed string instrument through historical records of Chinese Yazheng and music drawings. The analysis of various documents showed that Ajaeng originated from an ancient Chinese traditional musical instrument called Chuk. In terms of the performance style, the Chinese Yazheng had different musical forms depending on the purpose and location of the performance, and there was a method of standing up and fixing the musical instrument horizontally to the ground. Ajaeng in Korea has been handed down without much change in the form of musical instruments introduced in China during the Goryeo Dynasty and the way they sit on the floor and play on a pedestal. Through this study, we hope that it will help to preserve and develop traditional music and Korean traditional musical instruments by enhancing understanding of musical.

This paper is the first step to study on the acoustic characteristics of the Haegeum, a Korean traditional bowed-string instrument. We measured acoustic transfer functions of a Haegeum body using impulse response method. All the measurements are performed in anechoic chamber, INMC, SNU. We examined resonant characteristics of the Haegeum body with obtained transfer functions. Then we performed additional studies which are the Chladni pattern experiments and calculations of air cavity resonances to verify relations between the resonant peaks on the transfer functions and the resonances of each component, such as top plate, air cavity and so on. As a result, we can explain the acoustic characteristics of a Haegeum body and its components.
