Fantastical Prelude was actually the very first song I completed. I had, of course, a certain JRPG series in mind (a "Final" sort of fantasy, if you will!), and I worried that I would be a little too imitative.
But after finishing this, I was really happy with it. Then something funny happened. The melody stuck in my head FOREVER. Just repeated itself over and over again. Which is exactly what you want (but you can't predict which melodies will do that).
Part of it is a particular VST (virtual instrument) I used: "monomate," a monochromatic synth that has a mini-moog type of sound: deep and rich. It also doesn't process faster passages very well, creating charming processing errors that actually sound cool!
For some reason, I got it in my head that somewhere somebody would want to use this track to highlight some powerful scene in a romance/drama type of movie, and I would get this massive royalty from it (hah!). I guess I thought that because of the pretty, but melancholy flavor that it has.
