Without knowing anything at all about music theory, you can now create music thanks to Polyphonic, an app with which you can share music by following a color code.
Sounds grouped by colors
In Polyphonic you have to press the panel's squares, with each one representing a sound. In turn, they are divided by color groups and each one of them represents a different sound group. For instance, green is a sound, and each square with a different shade of green is a tone of that sound.
Very easy, but especially fun.
As you can see, it's a really simple system, as well as entertaining, so download Polyphonic Make Music for iPhone right now, and you'll create music in a very fun and quick manner, almost without noticing.
