This flute is made to the same specifications as the Shishida and Maruyama shinobue. It has excellent sound and high-pitched notes. Most beginners can play low notes, but they often struggle with high notes and even higher "pi" sounds. 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 notes, clear high-pitched notes, and affordable). It is recommended that beginners, rather than buying an expensive flute first, focus on being able to produce high notes and high-pitched notes, 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 clear high-pitched notes). Also, it seems that progress is faster if you start taking lessons after you can already play to some extent. 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 18.2 mm at the mouthpiece. Length: Approximately 40.9 cm Mouthpiece size: Approximately 14 mm The thickness is slightly thinner. (Thicker flutes have better low-frequency resonance, while thinner flutes have better high-pitched note sound.) Meat thickness: 2.4 on a scale of 5. (Thicker flutes have better high-pitched note sound and resonance, while thinner flutes are easier to play.) Pitch: Approximately eight-hon (a unit of length) weak. Range: Clear sound from the basic note (almost the "ro" note) to the fifth high-pitched note. About Yaki-take (Burnt Bamboo): This is the best sounding material among shinotake bamboo. Bamboo becomes harder and sounds better when it is thoroughly burned. However, there are few materials that meet the conditions, and it is difficult to process, which is a drawback. 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 Coating): Because no pigments are used in the paint, it is easier to produce sound. Also, by carving grooves inside and allowing the paint to soak in, it becomes even easier to produce sound and the sound quality improves. Please note: High notes and high-pitched notes are very easy to produce. 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. About discounts: Discounts are not possible due to the handmade nature of the product.
