I make shinobue flutes as a hobby, and they're well-regarded by the locals. ☆ミ They become sharp with a light breath! Especially the high-pitched notes have a metallic sound and a far-reaching tone.♪ This is a top-quality material for shinobue flutes! It's a slightly slender, four-hole key. Feel free to comment. Thank you! ☆ミ #ShinobueFlute #ClassicalStyle #FourHoleKey #Festival #Kagura #WindInstrument #SootBamboo
