This product is a bamboo pan flute used in South American folk music. As shown in the image, it has been repaired for some cracks. I believe it can be used without any problems. It is a product made by Blas, a musical instrument workshop in Lima, Peru. The lowest left "pipe," the longest, is about 32cm and has 22 pipes. The scale, starting from the longest pipe, is do (C4), re, mi, fa, so, la, si, repeating. I think it is easy to produce sound; there are no semitones. It can be used for playing. I have adjusted the images, but please understand that there may be differences before ordering. Folk music, Andean instruments, Inca, Sampoña.
