This item includes a mouthpiece adapter. With a recorder-like feel, you can play ~3 octaves!~, making it easier to grasp the concept of overtones! Even those unfamiliar with the shakuhachi mouthpiece can enjoy both. & Includes adapter! It's a G-key (G4~) Kena fingering for the shakuhachi mouthpiece, in the Do-Re-Mi scale♪ Made of female bamboo, it has a pattern and a tapered shape, making it a bamboo flute with a good resonance. Approximately 355mm in total length to the mouthpiece, mouthpiece - shakuhachi, inner diameter 20φ, tube end 10φ, Bolivian finger holes, 7.5～11.5φ holes, We have calculated the length and hole positions according to the inner diameter and hole diameter, and tuned it. The inside of the tube has been bored to 20φ. The shakuhachi mouthpiece is played by blowing outwards, but it produces a clear tone different from the Kena. I made it slightly deeper, so it sounds good and is easy to play. The adapter is made with a 3D printer. Recommended as a step to mastering the shakuhachi mouthpiece ♪ Bamboo is a natural material, so there may be knots, scratches, bends, etc. Please understand that this is a handmade item, and we appreciate your understanding. 242
