I did a simple google search and came up with this...
You probably have already been there.
I just realised what you are on about...
I have a Fair Trade Bird Water Ocarina... Exactly like this it only has the one hole to blow through.. and the bit to make the sound... I never knew there were other types.
Much better ✅
It's good that you took on the advice. 🙂
another link.. Ocarina Info
It has some links to tabs sites and stuff.. looks like a pretty helpful site.
I'm interested in getting one of these sweet potato ocarinas now.. hmm
My sis bought me the bird one because I got one on holiday in spain when I was 6 but when I brought it back home it fell into the bath and broke 🙁
and when my sis saw one last month she thought she'd buy it for my birthday.
It was just like getting a bit of my childhood back 😊
