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 is a bass wind instrument, descended from the cornet, and a distant ancestor of the tuba, with a mouthpiece like a brass instrument but side holes like a woodwind. It is usually a long cone bent into a snakelike shape, hence the name. This instrument is closely related to the cornet, although it is not part of the cornet family, due to the absence of a thumb hole. It is generally made out of wood, with walnut being a particularly popular choice. The outside is covered with dark brown or black leather. Despite wooden construction and the fact that it has fingerholes rather than valves, it is usually classed as a brass; the Hornbostel-Sachs scheme of musical instrument classification places it alongside trumpets.
