Thank you for viewing. This is a classic style, 5-hole flute made of smoked madake bamboo. * Tube length: 44.3cm * Diameter near the mouthpiece: 21.5mm, diameter near the end: 23mm * Mouthpiece size: 12.8mm (vertical) x 10mm (horizontal) * Inner surface coated with black lacquer * Reflector: beeswax This smoked madake bamboo was sourced directly from a famous bamboo shop in Kyoto. It has almost no bends, is nearly perfectly round, and the smoke stain is very dark, with almost no noticeable scratches. This is a very valuable piece of smoked madake bamboo. It is made of a hard material and tuned based on the Shishida scale. The mouthpiece and finger holes are not large, making it very easy to play. Also, because it is made of hard smoked madake bamboo, it has more volume and punch than a typical shinobue flute, and I think it can be recommended to anyone.
