This app encourages anyone to easily enjoy composing and experimenting with minimal music played by two people clapping their hands.
Abbreviating "Clapping Music Generator", that's "Cla-Gene!".
You can of course try changing the tempo and number of times the basic rhythm is used, but even using simple rhythms that you're familiar with may lead to wonderful encounters.

A free version (with limited functionality), "Cla-Gene! Trial Edition" is also available in the store.
