An ocarina is a small instrument that you can play with your hands. It looks like a little egg with holes on the top and a mouthpiece on the side. When you blow air into the mouthpiece and cover and uncover the holes with your fingers, it makes different sounds. It's kind of like a whistle or a flute, but it's much smaller and easier to carry around. Some people say it sounds like a bird. You can play lots of different songs on the ocarina depending on which holes you cover and how you blow into it. It's a fun way to make music and express yourself!
