Hey I've been playing this and am about to beat Act 4, but I'm stuck on one segment:
How to I get that piece of the Earthsong where the crown is shaking on the bottom and there is a musical line that I'm suppose to follow? The crown does 2 beats and I tried moving the right stick over to every direction when it shakes to the rhythm, but nothing happens. What am I suppose to do on this portion of the game?
I got passed that section now. Here's the answer: you should do something else than singing here.
Fully spoiled:
Stand below the line of beats and jump to the beats. Complete all chains of beats.
