What if you could create something musically amazing with just your voice? What if you didn't need musical instruments, sheet music, or complicated recording software? What if you could create an entire song with your voice, simulating bass lines, melodies, rhythms and sound effects, all in one pass, without ever stopping to think about it?
If you answered "that would be freaking amazing", then you need to download VoiceJam. VoiceJam is your access to performing, creating, and sharing amazing musical compositions.
