Wiz And Stirling
Stirling: Danke! Kind of a mix of homeschool and a bit of self taught. As I understand it, a synthesizer has a wider range, and is more intended to synthesize, while a keyboard is just for playing piano, with some other instruments for some reason. I don't actually know the answer well, being as I have little experience with synthesizers and the terminology there :p  In the case of that piece, I just hooked up a small keyboard with no built in instruments into a computer and used garage band of all programs.
Wiz: Thanks for the wishing good luck, I'll probably fail miserably though :p I mean, it's a mix of epic and crazy! HOW DO I DO THAT? BECAUSE YOU CAN'T HAVE CONSTANT LOUDNESS! AHHHHHH HEAD EXPLODING! *Theo's brain explodes, and Simmons starts mopping it into a bin and then pours it back into Theo's head* Oww..... If you like, I can make some sheet music for your friend if you'd prefer real instrument to synthesizer :p
