Hi, I have made quite a few "Ocarinas", but not designed for musicians, but rather curio collectors. I started to look into making well tuned ones, but for the place and time i was in, it did not seem worthwhile. I am getting ready to get going with clay again, and I might give tuned ocarinas a try again. Would love to see your site if you have one. Here is a picture of some of the ones I made: http://zafka.com/w5.html This next page shows some stages in making them, nothing to do with the actual sound making. http://zafka.com/fish_photos.html
