This flute is made to the same specifications as the Shishida and Maruyama shinobue flutes. This flute produces a good sound with excellent resonance and clarity. Despite being slightly thicker, it also produces high-pitched sounds well. 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 a good sound. I have discovered that only bamboo that meets certain conditions will produce sound on its own. Thickness: Approximately 23.5 mm at the mouthpiece Length: Approximately 50.7 cm Mouthpiece size: Approximately 15 mm Bamboo hardness: 2.3 on a scale of 5 Thickness: Slightly thick Pitch: Approximately between 3.5 and 4 hon (a unit of pitch) Range: Beautifully clear from the basic tone to the high-pitched sound 5. It is made based on the standard fingering of a shinobue flute. Special fingerings and high-pitched sound 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 village Shinto music, which are designated as intangible cultural properties, originally used Wa-bue (bamboo flute) (it is a uniquely Japanese transverse flute). Features: It is characterized by the use of madake (Japanese timber bamboo) and hachiku (a type of bamboo), which have 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, being used in various festivals and village Shinto music. 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 craftsmen in the country. (Because it is the most difficult to make, there are very few craftsmen who can play and make it) 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 do not ask for a price reduction.
