The shinobue ( kanji: 篠笛; also called takebue ( kanji: 竹笛)) in the context of Japanese traditional arts) is a Japanese transverse flute or fue that has a high-pitched sound. It is found in hayashi and nagauta ensembles, and plays important roles in noh and kabuki theatre music. It is heard in Shinto music such as kagura-den and in traditional Japanese folk songs. There are two styles: uta (song) and hayashi (festival). The uta is properly tuned to the Western scale, and can be played in ensembles or as a solo instrument. The hayashi is not in the correct pitch, because it is simply a piece of hollow bamboo with holes cut into it. It emits a very high-pitched sound, and is appropriate for the festival/folk music of Japan. Both shinobue flutes play a very important role in the Japanese theater.
