|Quena Flute (images from wikipedia)|
It's a quena flute picture, i get the picture from wikipedia. Traditionally quena flute made by bamboo or wood. I find a video in youtube about how to make quena, in this video made from wood. I think you can follow the step to make it if you have tools like in the video. But i think if you didn't have tools, you can use bamboo or pvc pipe to make quena. I think that materials very easy be formed.
Okay enjoy this video guys.
