An Ocarina is a small, simple wind instrument
shaped like a potato. It is usually made out of terracotta, a European pottery
material, or carved from wood. If it is made from clay, it must be tuned when
the clay is still wet. The Ocarina has finger holes and a mouth piece and come
in all different sizes, the larger ones having a mellow, hollow tone. The
Italians adopted it as a folk instrument because they loved its sweet, haunting
tone.
