This flute is made to the same specifications as the Shishida and Maruyama shinobue flutes. It is easy to play and produces a good sound. It also supports the fingering for the second and third holes from the bottom. Most beginners can play low notes, but they often 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 sound. This flute was made based on the opinions of instructors from various regions (focusing on ease of producing the "ko-on" and "dai-ko-on" sounds, and affordability). It is recommended that beginners, rather than buying an expensive flute first, learn to produce the "ko-on" and "dai-ko-on" sounds, then go to a shop and try out different flutes to find one that suits them. (Some flutes may look good but not produce the "dai-ko-on" sound). It seems that progress is faster if you start taking lessons after you can play some notes. To prioritize ease of playing, sound quality, resonance, and affordability, there may be scratches, natural shapes, natural patterns, and natural bends. A 10mm ball is placed in the image for reference of the hole size, etc. Thickness: Approximately 21.2mm at the mouthpiece. Length: Approximately 45.5cm Mouthpiece size: Approximately 15mm Thickness: Normal (Thicker flutes have better low-frequency resonance, while thinner flutes produce better "dai-ko-on" sounds) Wall thickness: 2.3 on a scale of 5 (Thicker walls produce better "dai-ko-on" and sound, while thinner walls are easier to play) Pitch: Approximately between 4.5 and 5 hon Range: Produces clear sounds from the "tsutsune" (ro-on) to "dai-ko-on" 5. What is "yaki-take" (burnt bamboo)? It is the best sounding material among shinobue bamboo. When the bamboo is thoroughly burnt, it becomes hard and produces a good sound. 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.) What is "sukinuri" 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 sound quality improves. Please be aware: The "ko-on" and "dai-ko-on" sounds are very easy to produce. When playing strongly, make sure there are no people around. Especially be careful of small children, the elderly, people with disabilities, and those who are not feeling well.
