This is an Aulos Ocarina AOC-4 Alto C. Compared to easier-to-play ocarinas, it requires more (stronger) breath, and the high notes produce a powerful, clear tone. (Weak breath will result in a breathy sound.) It has a flat shape that fits comfortably in the hand. There is some dirt from use, but it does not affect the performance. The "AULOS" logo on the body is difficult to see because of the extra glaze, but it is definitely an Aulos ocarina. Aulos ocarinas are fully-fired ocarinas, so the sound is easy to focus, but they tend to condense in low temperatures, so it is necessary to remove moisture from the airway. The new retail price on online shopping sites is around 20,000 yen. A Soprano F ocarina is also available (not listed, in better condition than the Alto C). Please comment if you are interested. We will offer a discount if you want to purchase them as a set. Included: Soft case
