This flute is made to the same specifications as the Shishida and Maruyama shinobue flutes. It also supports the fingering for the second and third holes from the bottom. Most beginners can play the low notes, but many seem unable to play the high notes or the even higher "pii" sound. Many people are also unsure if the flute they are currently using is actually producing the correct sounds. This flute was made based on the opinions of instructors from various regions (easy to produce high notes, clear high register notes, and affordable). It seems that beginners are advised to first learn to produce high and high register notes before buying an expensive flute, 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 register notes). Also, it seems that progress is faster if you start taking lessons after you can play to a certain 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. Thickness: Approximately 20.5 mm at the mouthpiece. Length: Approximately 42.6 cm Mouthpiece size: Approximately 15 mm Thickness: Normal (Thicker flutes have better low-frequency resonance, while thinner flutes have better high register note clarity) Wall Thickness: 2.2 on a scale of 5 (Thicker walls result in better high register notes and sound, while thinner walls are easier to play) Pitch: Approximately equivalent to a "roku-hon-jaku" (six-hole) flute. Range: Clear sound from the "tsutsune" (low register) to the fifth high register note. About Yaki-take (Burnt Bamboo): This is the best material for sound among shinobue bamboo. Bamboo becomes harder and sounds better when thoroughly burned. However, there are few materials with the right 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 of utilizing natural principles 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 be aware: High and high register 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. Regarding discounts: Due to being handmade, discounts are not possible.
