I bought this is Tel Aviv many years ago.. I can produce clear notes but, not a tune....
The okarina is an ancient wind musical instrument—a type of vessel flute. Variations exist, but a typical okarina is an enclosed space with four to twelve finger holes and a mouthpiece that usually projects from the body. It is traditionally made from clay or ceramic.
oh, this poor little rhino (if it is one) is looking worried about his body holes! I had a 'flute' given to me a bit like this and I just can't produce a note!
