I don't know how this kind of flute is called. I found it in a market in Chinchero, Peru. It had a very beautiful and warm sound but I was in doubt if buying it or not, because I already bought a charango, two quenas, the chapchas and the horn. I was just playing it and talking to the seller, and I was not able to decide. So my wife told me: "Come on, you know you will buy it, buy it quickly and don't waste our time!"... :)
