The Institute periodically exhibits panels at the entrance lobby so that all visitors can see our research results. Starting at the end of March, we have been introducing the results of radiography study on flutes used in Noh, Nohkan. The Nohkan delivers a unique sharp tone: To do so, the inner diameter between the mouthpiece and the first ventage has been narrowed as an artifice. The subsequent crafting technique was conventionally known: An additional material called “nodo (throat)” was inserted into this portion to narrow the inner diameter. However, X-ray photography discovered several old Nohkan flutes whose inner diameter had been narrowed without inserting “nodo”. One researcher put forward the view that Nohkan was derived in the process when a broken Ryuteki was repaired by inserting a tenon. However, this theory must now be revised as a result of this X-ray photography conducted. With this exhibition, we are making preparations so that the sound from an old Nohkan can be heard, and we are also exhibitingthe X-ray photo of the Ryuteki housed in the Buddha statue in the Kamakura period. We are very happy that this exhibit allows people to actually hear Japanese traditional music.
