This paper examines the acoustical characteristics of the ornaments of the Singing Voice in Koto (Japanese Harp) and Shamisen (Japanese Guitar) music. The ornaments of Koto music are‘furi’(shake),‘atari’ (push),‘suriage’(slowly up),‘sun-sage’(slowly down), etc.‘Atari’and‘furi’are the glottal techniques. In the cases of‘sun-age’and‘sun-sage’the target tone is specified, and the fundamental frequency changes continually. On the contrary, in the cases of‘atari’,‘furi’, no target tone is specified, the power decreases while the fundamental frequency increases. The change in fundamental frequency is not continuous. Controll of the glottis may differ between the various techniques.
