Thank you for viewing. This is the Quena workshop "Fumu" in Mito City, Ibaraki Prefecture. This time, I made a quena from thick Peruvian bamboo. There are only three available. The inner diameter near the mouthpiece is just under 18mm, the largest sound hole is 10mm, and the mouthpiece width is 9mm. It is tuned to A = 442Hz Bolivian tuning. There are three specifications, and we will sell one for 12,000 yen including shipping.
