This flute is made to the same specifications as the Shishida and Maruyama shinobue flutes. It is easy to play and produces good high-pitched sounds. Most beginners can play low notes, but many 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 high-pitched sounds, clear high register, and affordable). It is recommended that beginners, rather than buying an expensive flute first, focus on being able to produce high-pitched sounds and the high register, and then go to a shop to try out flutes and buy one that suits them. (Some flutes may look good but not have a clear high register). Also, it seems that progress is faster if you start taking lessons after you can play some notes. 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 20mm at the mouthpiece Length: Approximately 48.7 cm Mouthpiece size: Approximately 14.5mm Slightly thinner in thickness (Thicker flutes have good low-frequency resonance, while thinner flutes have good high-register sound) Wall thickness: 2 on a scale of 5 (Thicker walls produce good high-register sound and resonance, while thinner walls are easier to play) Pitch: Approximately between 4.5 and 5 hon (a Japanese musical scale) Range: Clear sound from the root note (ro-on) to the high register 5 About Yaki-take (Burnt Bamboo): This is the best material for sound among the shinodake bamboo. Bamboo becomes harder and produces better sound when it is thoroughly burned. However, there are few materials that meet the conditions, and it is difficult to process. It is also characterized by even better sound 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 that meets 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 be aware: High-pitched sounds and the high register are very clear. When playing strongly, please make sure there are no people around. Please be especially careful with small children, the elderly, people with disabilities, and those who are not feeling well. Regarding discounts: Due to being handmade, discounts are not possible.
