This flute is made to the same specifications as the Shishida and Maruyama shinobue flutes. It is a phantom 7-hole, 0-hon choshi flute. It is a very rare item. This flute has small finger holes, making it easy to play, and has relatively good balance, producing good high-pitched sounds. As it is handmade using natural materials, there are natural shapes, patterns, bends, and scratches. The volume (it makes 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 sound good. I have discovered that only bamboo that meets certain conditions will produce sound on its own. Thickness: Approximately 24.2 mm at the mouthpiece Length: Approximately 60.4 cm Mouthpiece size: Approximately 16 mm Bamboo hardness: Slightly soft Thickness: Slightly thin Pitch: About 0.5 hon Range: Beautifully clear from the tube sound to the highest note (dai-kan-on) 5. It is made based on the standard fingering of shinobue flutes. Special fingerings and dai-kan-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 makers in Kyoto since the Heian period and has been passed down throughout the country. Wa-bue (bamboo flute) is the original form of the hayashi (festival music) 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 ha-chiku (thin bamboo), 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 hayashi 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 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.
