The mouth harp is a small folk instrument also known as a jaw harp or jew's harp. When you hold it to your mouth and change the size of your mouth cavity, the sound of the instrument changes, similar to a guitar played through a "wah wah" pedal.
To play the mouth harp app:
1) Touch the iPhone screen to your lips.
2) Tap the thin end of the mouth harp to hear a "twang" sound.
3) Move your lips further apart or closer together to change the frequency response of the sound.
If you're having trouble, tap the (?) icon to show the "hot spots" on the screen.
