I've never had music theory... I suppose I'll be taking some of those classes soon though. Although, nearly anything you learn in Music Theory I you can pick up yourself after writing music for so long.
ex. d minor is supposedly the "saddest" key of them all, while C Major is the "happiest". Supposedly E Flat Major is used in a lot of "heroic" songs, and so on and so forth.
What I mean is, music theory is definately useful, but you don't have to have it to become good at composing. I haven't had it yet, and I'm pretty good (so I think anyway), and I'm sure arlen and Silverline haven't had any theory classes either.
As for the song, thanks. It's no big deal really.
