Two of the younger 60minute sons really love video games. I've had a good time introducing them to classic games from time to time (ok, mostly so I have a chance to not get my brains beat in when I try to play). One of their favorites was "The Legend of Zelda: Ocarina of Time". It's kind of the "Sgt. Pepper's" of Nintendo games; a game just about everyone would put in their top-5 list.
Well, one of the 60minute sons was so into the game that he took up playing a real ocarina. He researched it, found a company online that makes porcelain ocarinas, ordered it and taught himself how to play. It's no longer allowed in the car, but other than that, it was fun to watch him take on a new challenge.
He taught himself by finding fingering charts on the Internet, much like you would do for tabs for guitar. This also means there are others in the world who spend time and energy on the ocarina. Enough so to make fingering charts. Truly scary!
Of course, it occurred to me that fingering charts would also make a good puzzle cache. (I recognize that others may find me truly scary as well)
Solving the puzzle
The following charts are for 10-hole ocarinas. Each note corresponds to a number in the cache coordinates. If you play the coordinates on an actual ocarina, you'll be magically transported directly to the cache. Or not.
You can validate your puzzle solution with certitude.
