“…Afterwards, Kwon et al discovered the vibration mode of Jing and the natural frequency through the acoustic analysis using the planar acoustic holography and accelerometer, and observed a rotating energy phenomenon at a specific frequency [6]. Also, researches were conducted on how to construct Korean gong and its acoustic characteristics [7], on sound amplification and duration according to the depth of rim [8], as well as on the detection of eigen frequency from gong sound using ensemble empirical mode decomposition [9]. Likewise, most studies until now have focused on discovering vibration modes and natural frequencies.…”

Abstract. This paper describes a basic synthesis model based on the KS algorithm for metallic percussion instrument. Unlike other percussion instruments, Korean metallic percussion instrument called Jing have a precise harmonic structure that is characteristic of stringed instruments. In addition, each harmonic exhibits a frequency gliding phenomenon called softening according to the intensity of the deriving, and irregular non-linearity called hardening for some partials. Therefore, the proposed synthesis model applies KS algorithm for harmonic structure and KS algorithm with time-varying propagation speed for irregular nonlinearity, hardening.

“…Among them, the representative percussion similar to the Korean percussion instruments, Jing, is a Chinese gong and many researches of that one have been reported [1][2][3][4]. The researches on the Korean Jing and Balinese gamelan gong have been also reported [5][6][7][8]. One of them introduces beat phenomena of the Jing, which is one of the unique characteristics of the Korean metallic percussion.…”
