Material: Shinobue bamboo Number of finger holes: 7 Key: 8 hon, Doremi scale (Key: C) Finish: Exterior: Cashew lacquer, transparent brown; Interior: Cashew lacquer, red Dimensions: Total length: approx. 402mm; Mouthpiece outer diameter: approx. 18.8mm; End outer diameter: approx. 16.5mm I make and play shinobue flutes for local festival music, and I have created this shinobue tuned to the Doremi scale. You can enjoy Western-scale songs like J-POP, so why not give it a try? Due to the natural materials, there may be some warping or stains unique to the material, but we hope you will appreciate it as part of the character of the material.
