I used my musc theory skills to beat this. It was really hard, because even though the bubbles were colored, it was still easy to lose track on what bubble you hit last. I kinda cheated too, I used my keyboard for some of the leaps. It took me 20 minutes or so to do. It was a great game, and think there should be one extra level that would have a 50 note melody. That would be pretty kickass.
