Apps have done wonders for music creation, and now there's mobile software from Casio that aims to make it even easier. The Chordana Composer app for iPhone creates a track basked on a melody that you create by singing or whistling two bars of a tune. Casio's handiwork records you, and then automatically builds the rest of the song based on your input. This means that anyone can construct a hit without in-depth music knowledge or the ability to play an instrument. After the base of the song is captured, there's five genres and three melodic settings for the tweaking before hitting the Auto Compose button and putting the app to work.
