True-Love lived for a time in Loas. He had one made for a friend. Paid $7. He rather thinks they sound like an organ. Unearthly sound though, and very loud. It's a collection of bamboo stems, of different lengths, tied together with raffia. The mouth piece surrounds the stems and helps keep the whole thing in shape. They have reeds inside the bamboo. No strings. They're played in Southern China too. Cheers, Joy
