My instrument is in the string family. It has three strings. There are three different lengths of string.

It is made with:

A coffee can, three pieces of string, a stopper, and a piece of wood.

Here's how I made it:

I got a coffee can and my Dad drilled three holes in the can. Then I put three pieces of string through the holes. I put one stopper on the end of the strings inside the can. I brought the strings up, and tied them to a piece of wood.
