Hello all! I'm new to this forum, and have a question about a flute I found at a neighborhood sale. I thought for a while that it was ornamental since it was in a display case, but after I opened it, it appears to be similar in structure to the Chinese Bamboo Dizi flutes. However, the material is closer to granite, and the Dizi fingering charts online don't seem to fit. I've posted a picture below -- if anyone has thoughts on fingering charts for this or any information in general I would love to hear it. (Bandaid is acting as the di mo membrane since I didn't have any tape handy)
