What hardware is supported?
The Mouth Harp has been tested on iPhone (1st gen), iPhone3G, iPhone4 and iPad. It is compatible with OS 3.1 and later. It should work with iPod touch as well, you might need to use earphones to get sound.

What are good playing techniques?
Swipe your finger across the screen. When you release, the sound is played. The volume is dependant on the length of your flick. When you tilt the device, you can hear the overtones change. Tilt it left to get higher pitched harmonics and right for deeper sounds.
When you touch the screen the sound is silenced. This is used in real life to create rhythms and stacatto, short tones.

How does holding the device to your mouth work?
When you hold your mouth next to the speaker, the sound resonates inside your mouth cavity. Try moving and shaping your throat while playing the instrument. You can hear the sound changing when you close up your throat, breathe and make different vowel shapes (oohs, aaahs, iiiihs) with your mouth.
Set the instrument to Flat Mode when controlling the sound with your mouth for better control!

The instrument stutters/lags a bit after loading?
On older devices it takes a while for all the audio channels to be set up. The app contains a multitude of samples, requiring the device to set up everything to work smoothly. If you experience this, just wait a couple of seconds and it should be smooth sailing when everything is loaded.

The sound of the harp is strange/deep/too high?
You can adjust the pitch in the settings menu. Just tap the little information icon in the left corner and use the slider to set the pitch to your liking.

I have another question.
Please contact support(at) with any enqueries.
