This flute is made to the same specifications as the Shishida and Maruyama shinobue flutes. This flute is easy to play and produces a clear high-pitched 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 have discovered that only bamboo that meets certain conditions will produce sound on its own. Thickness: Approximately 21.5 mm at the mouthpiece Length: Approximately 45 cm Mouthpiece size: Approximately 14.5 mm Bamboo hardness: Normal Thickness: Normal Pitch: Approximately six hon (a unit of pitch) Range: Beautifully clear from the fundamental tone to the fifth octave. It is made based on the standard fingering of a shinobue flute. Special fingerings and fingerings for the high-pitched sounds 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 makers in Kyoto since the Heian period and has been passed down throughout the country. The traditional music of the intangible cultural heritage, Satokagura, originally uses Wa-bue (bamboo flute) (a transverse flute unique to Japan). Features: It is characterized by the use of madake (Japanese timber bamboo), hachiku (Pleioblastus chino), etc., 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 local hayashi (musical ensembles) and Satokagura. 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 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.
