It is very difficult to sing with the explanation about how to vocalize musics in the KUN-KUN-SI ; a classical music textbook by of Nomura Group, and it's not easy to follow teacher's explanation as well. We analyzed ten teacher's singings, and found out the structure of their voice. With this finding, we now think that it will be more helpful to understand how to vocalize 'SEI-GAKU-FU' and 'UFU-GAKI'.
But it is not enough to sing UFU-GAKI, to ten teachers, we asked their opinions and thoughts about 'UFU-GAKI'. Then we got some images and hints about it, it is not only "up and down of frequency". Inside throat, a singer moves his vocal chords and the inter-space complexly. and this vocalization makes voice rich and relish good sounds.
This is to report on the structure of UFU-GAKI and some comments
