This flute is made to the same specifications as the Shishida and Maruyama shinobue flutes. It is easy to play and supports fingerings that cover the second and third holes from the bottom. Most beginners can play low notes, but they often struggle to play high notes or the even higher "pi" sound. Many people are also unsure if the flute they are currently using is actually producing the correct sounds. This flute was created based on the opinions of instructors from various regions (easy to produce "ko-on" (high notes), clear "dai-ko-on" (very high notes), and affordable). It is recommended that beginners, rather than buying an expensive flute first, learn to produce "ko-on" and "dai-ko-on" and then go to a shop to try out different flutes to find one that suits them. (Some flutes may look good but not produce "dai-ko-on"). Also, it seems that progress is faster if you start taking lessons after you can already produce some sounds. To prioritize ease of playing, sound, resonance, and affordability, there may be scratches, natural shapes, natural patterns, and natural bends. A 10mm ball is placed in the image. Please use it as a reference for the size of the holes, etc. Thickness: Approximately 21.5mm at the mouthpiece. Length: Approximately 47.9 cm Mouthpiece size: Approximately 14.5mm Thickness: Normal (Thicker flutes have better low-frequency resonance, while thinner flutes produce better "dai-ko-on") Wall Thickness: 2.2 on a scale of 5 (Thicker walls produce better "dai-ko-on" and resonance, while thinner walls are easier to play) Pitch: Approximately 4.5 to 4 hon (a unit of measurement for flute pitch) Range: Clear sound from "tsutsune" (low notes) to "dai-ko-on" 5. About Yaki-take (Burnt Bamboo): This is the best material for sound production among shinobue bamboo. Bamboo becomes harder and produces better sound when thoroughly burned. However, it is difficult to process due to the scarcity of suitable materials. It is also characterized by even better sound production when made naturally. Bamboo grows by competing for light. Therefore, the bamboo that wins the competition for light is the most suitable for flutes. (I have been researching physics utilizing the laws of nature for many years, so I can identify bamboo with the right conditions.) About Suke-nuri Finish (Transparent Lacquer Finish): Because no pigments are used in the lacquer, it is easier to produce sound. Also, by carving grooves inside and allowing the lacquer to soak in, the sound becomes even easier to produce and the resonance improves. Please note: "Ko-on" and "dai-ko-on" are very easy to produce. When playing strongly, please make sure there are no people around. Especially be careful of small children, the elderly, people with disabilities, and those who are not feeling well. Regarding discounts: Due to being handmade, discounts are not possible.
