This flute is made to the same specifications as the Shishida and Maruyama shinobue flutes. This flute has smaller finger holes, allowing for good high-pitched sounds. As it is handmade using natural materials, there may be natural shapes, patterns, bends, and imperfections. The volume (it can make your ears tingle) and sound quality are superior to shinobue flutes. I have been researching physics for a long time. I have succeeded in selecting materials that are easy to play and produce good sound. I discovered that only bamboo that meets certain conditions produces sound on its own. Thickness: Approximately 20.1 mm at the mouthpiece Length: Approximately 43.8 cm Mouthpiece size: Approximately 13.5 mm Bamboo hardness: Slightly harder than normal Thickness: Normal Pitch: Approximately six and a half Range: Beautifully clear from the fundamental tone to the fifth octave. It is made based on the standard fingerings of a shinobue flute. Special fingerings and high-pitched note fingerings may vary depending on the region. It is recommended to confirm in the comments. About Wakue (Japanese Bamboo Flute) A transverse flute made by flute makers in Kyoto since the Heian period and passed down throughout the country. Wakue (bamboo flute) is the original form of the hayashi (musical accompaniment) and satokagura (village Shinto music) designated as intangible cultural properties. (It is a unique Japanese transverse flute.) Features: It is characterized by the use of madake (Japanese timber bamboo) and hachiku (Pleioblastus amarus), etc., with nodes. It is also called a bamboo flute. It reached its peak from the mid-Edo period to the Taisho era and spread throughout the country, used in hayashi and satokagura in various regions. However, it declined from the end of the Taisho era to the Showa era. Around this time, Shishida brand shinobue flutes spread throughout the country, and the Wakue, which was difficult to play and expensive, seemed to have lost to the shinobue. The origin of Wakue (bamboo flute) is in Kyoto, and the origin of shinobue is in Tokyo. (Kyoto bamboo flute, Edo shinobue) (Dragon bamboo flute, Lion shinobue) There seem to be only a few Wakue craftsmen in the country. (Because it is the most difficult to make, there are very few craftsmen who can play and make them) It seems to be quite expensive. (Around 50,000 yen) I am committed to making Wakue that are as easy to play and sound good as possible at a reasonable price. Please refrain from price reductions.
