This is a Ko-rai AG triple ocarina. It has been slightly shaved to help with finger placement, as you can see in photo 2. It has a rich tone, and unlike other triples, you can use the finger positions of a single ocarina on all three pipes. This is the ocarina that Mr. Zhou confirmed and is shown in the photos after his. Also, in the key of C, the notes B and A are played with breath control. I am selling it because I can't play multiple pipes. - Model Name: Ko-rai AG Triple Ocarina - Color: Dark Brown - Number of Holes: Pressing the W sound holes - Design: Triple Pipe - Mr. Zhou Zilei tested and confirmed this pipe. Photos are included. Thank you for looking.
