Handmade Quena - Front 6 holes (8 holes), Back 1 hole Key of D (D4～) Do-Re-Mi scale ♪ Made from a rare long tube (598mm) of Hotei bamboo. The bamboo's tortoise shell pattern is very unique. The base tube is B, but it's made with D key finger holes. The pitch of the finger holes isn't wide, making it easy to cover. The bottom 2 holes are for tuning (pressing them will produce the lower notes B～C#). The inner diameter is basically 22φ, bored out. The finger holes are 7.5～11.5mm, making it a flute with a large volume, typical of a long tube. From the mouthpiece, the specifications are approximately: total length 598mm, mouthpiece 9mm, inner diameter 22φ, tube end 10φ. Like a long tube, it has a good bamboo flute sound. I think it's very easy to play (*^^)v The bamboo is a natural material, so there may be knots, scratches, and bends. It's handmade, so please understand. *The Siku is not included...289
