This flute is made to the same specifications as the Shishida and Maruyama shinobue. This is a banana tube, so it has excellent sound and high-pitched notes. This flute was made based on the opinions of instructors from various regions (easy to produce high-pitched notes, clear high-pitched notes, and affordable). Using pigments makes the walls thicker and increases the volume. 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 20.5mm at the mouthpiece Length: Approximately 44.8 cm Mouthpiece size: Approximately 13.5mm Thickness: Normal (Thicker flutes have better low-frequency resonance, while thinner flutes have better high-pitched note sound.) Wall thickness: 2.3 on a scale of 5 (Thicker walls produce better high-pitched notes and sound, while thinner walls are easier to play.) Pitch: Approximately between 5.5 and 6.0 hon (a unit of measurement for flute pitch) Range: Clear sound from the tube note (ro-on) to the high-pitched note 5. About Yake-take (Burnt Bamboo): This is the best sounding material among shinobue bamboo. Bamboo becomes harder and sounds better when thoroughly burned through. 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 the physics utilizing the laws of nature for many years, so I can identify bamboo that meets the right conditions.) Please be aware: High-pitched notes and high-pitched sounds 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. Regarding discounts: Discounts are not possible due to the handmade nature of the product.
