The Geocache is NOT at the posted coordinates!!

You must correctly identify the featured musical instrument to get the correct set of coordinates. Type in the correct name of the instrument. Four choices are listed. One of them is the right one.

This instrument is a lamellophone instrument, consisting of a flexible metal or bamboo tongue or reed attached to a frame. The tongue/reed is placed in the performer's mouth and plucked with the finger to produce a note. Each instrument produces one pitch only, with its multiples (overtones), though different sized instruments provide different pitches. There is no standard pitch.
