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.

Pretty cool game
My mom walked in and gave me the the death stare then ran out when I was doing this and probably thought I was making out with my phone 😂😂😂😂😂 all though it is (hard) to make the boing sound with your lips so I just used my finger and still did not work???????
Needs work. I can already use the iPhone speaker in my mouth to make fun sounds. So the lips on screen doesn’t work. Needs to be able to choose a key. Worth some time on the developers part.
This app is frigging sick all it is is a basic mouth harp which is all I wanted!!! those look like mouth harps right??!! lol
