This flute is made to the same specifications as the Shishida and Maruyama shinobue flutes. This flute is easy to play and produces good sound. As it is handmade using natural materials, there may be natural shapes, patterns, bends, and scratches. The volume (it can be piercing to the ears) 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 sound good. I discovered that only bamboo that meets certain conditions produces sound on its own. Thickness: Approximately 19.8 mm at the blowing hole Length: Approximately 40.5 cm Size of the blowing hole: Approximately 14 mm Bamboo hardness: Normal Thickness: Normal Pitch: Approximately six and a half hon Range: Beautifully clear from the tube tone to the Daikou-on 5. It is made based on the general fingerings and fingering charts of the shinobue flute. Special fingerings and Daikou-on fingerings may vary depending on the region. It is recommended to confirm in the comments. About Wa-bue (Japanese Bamboo Flute) It is a transverse flute made by flute makers in Kyoto since the Heian period and has been passed down throughout the country. The traditional music of festivals and Satokagura, which are designated as intangible cultural properties, originally used Wa-bue (bamboo flute) (a unique Japanese transverse flute). Features: It is characterized by the use of madake (Japanese timber bamboo), hachiku (thin-stemmed bamboo), 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 various festivals and Satokagura. 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 difficult-to-play and expensive Wa-bue seemed to have lost to the shinobue. The origin of Wa-bue (bamboo flute) is in Kyoto, and the origin of shinobue is in Tokyo. (Kyoto's bamboo flute, Edo's shinobue) (Dragon's bamboo flute, Lion's shinobue) There seem to be only a few Wa-bue 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 Wa-bue that are as easy to play and sound good as possible at a reasonable price. Please refrain from price reductions.
