If you took the ocarina from The Legend of Zelda OoT/MM and made it the main focus... I Love it! I like how the rage mechanic temporarily disables one of your notes, forcing you to use the other spells; however, I find that it keeps interrupting me while I'm at the end of the level, trying to learn the key song. I hope you someday look further into the concepts you presented in Songbird, and compose (ha) something even more in-depth and brilliant out of it!
