This flute is made to the same specifications as the Shishida and Maruyama shinobue flutes. This flute is easy to play and feels similar to a shinobue, producing 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 produce good sound. I discovered that only bamboo that meets certain conditions can produce sound on its own. Thickness: Approximately 20.5 mm at the mouthpiece Length: Approximately 45.2 cm Mouthpiece size: Approximately 14.5 mm Bamboo hardness: Slightly softer than normal Thickness: Normal Pitch: Approximately six-hon-jaku (a Japanese musical scale) Range: Beautifully clear from the tube sound to Daikou-on 5. It is made based on the general fingering and finger techniques of the shinobue. Special finger techniques and Daikou-on fingerings may vary depending on the region. It is recommended to confirm in the comments. About Wa-bue (Japanese flute) It is a transverse flute made by flute artisans in Kyoto since the Heian period and has been passed down throughout the country. The traditional music of O-bayashi 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) and hachiku (Pleioblastus chino) with nodes. It is also called a bamboo flute. It reached its peak from the mid-Edo period to the Taisho period and spread throughout the country, used in O-bayashi and Satokagura in various regions. However, it declined from the end of the Taisho period to the Showa period. Around this time, Shishida brand shinobue flutes spread throughout the country, and the difficult-to-play and expensive Wa-bue seemed to have lost out 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 artisans in the country. (Because it is the most difficult to make, there are very few artisans 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.
