This flute is made to the same specifications as the Shishida and Maruyama shinobue. Because it's a banana tube, the high-pitched "dai-kan" sound has punch. Most beginners can play the low notes, but they often can't play the high notes or the even higher "pii" sound. Many people are also unsure if the flute they are currently using actually produces the correct sounds. This flute was made based on the opinions of instructors from various regions (easy to produce high notes, clear "dai-kan" sound, and affordable). It seems that beginners are advised to first learn to produce the high and "dai-kan" notes before buying an expensive flute, and then go to a shop and try out different flutes to find one that suits them. (Even if a flute looks good, it may not produce the "dai-kan" sound.) Also, it seems that progress is faster if you start taking lessons after you can already 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 19.5mm at the mouthpiece. Length: Approximately 44.8 cm Mouthpiece size: Approximately 15mm Thickness: Slightly thicker (Thicker flutes have good low-frequency resonance, while thinner flutes have good "dai-kan" sound.) Meat thickness: 2.2 on a scale of 5 (Thicker meat produces good "dai-kan" sound and resonance, while thinner meat is easier to play.) Pitch: Approximately six and a half to seven hon (a unit of measurement for flute pitch) Range: Clear sound from the "tsutsu-ne" (low register) to "dai-kan" 5. About Yaki-take (Burnt Bamboo): This is the best material for sound among shinobue 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 (Transparent Coating) Finish: 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, the sound becomes even easier to produce and the resonance improves. Please be aware: The high and "dai-kan" notes are very easy to produce. When playing strongly, please make sure there are no people around. Please be especially careful around small children, the elderly, people with disabilities, and those who are not feeling well. About Discounts: Because this is handmade, discounts are not possible.
