The Triple-Banded Acoustic
 
The name of my instrument is “The Triple-Banded Acoustic.” The family my instrument belongs to is the string family.

The materials used to make my instrument were plywood and three rubber bands.

My instrument produces sound by strumming or plucking the rubber bands, which then either produces a high or low pitch.

In order to change pitch, volume, or sound depends on the force or tension that is applied to the rubber bands. It also depends on how long, short, thick, or thin the rubber bands are.
