The ED-Harp

The ED-Harp is made out of duct tape, string, 3 rulers, rubber bands
and Saran wrap.

It is a member of the orchestral string family.

When you pluck the string it vibrates onto he Saran wrap producing the
sound.

The longer strings are lower and the shorter ones are higher.

To change the volume, the more pressure your hands put on the string,
the louder it will be.
